You can have the fastest search engine in the world, but if it doesn’t show the right results, users won’t stick around.

That’s where search relevance comes in. It connects user intent to real outcomes, such as clicks, conversions, and continued engagement.

In this guide to search relevance, we will cover:

* What search relevance means
* Why relevance affects user satisfaction, conversions, and engagement
* What factors and signals influence search engine ranking
* How to measure relevance using metrics like precision and recall
* Common challenges like noisy data, ranking issues, and limited resources
* Practical ways to improve search results relevance using ranking rules and algorithms
* How Meilisearch helps you build a fast, relevant, and scalable search experience

Want your users to find exactly what they’re looking for? Let’s get into it.

## What is search relevance?

Search relevance refers to how aligned a search result is with a user’s query intent. It measures how well the search result matched the user’s query and provided the information they were looking for. 

High relevance means the top results are timely, accurate, and context-aware.

Modern search engines use algorithms that factor in ranking signals, query intent, and language models to determine relevance. When relevance is high, users find what they need faster, leading to higher engagement and lower bounce rates.

## Why does search relevance matter?

Search relevance is the backbone of a good search experience. When users get results that match their intent, they stay longer, click more, and convert faster – pretty much everything a business wants. 

On the other hand, irrelevant results cause users to leave immediately, which rapidly increases bounce rates.

In e-commerce, relevant search helps customers find the right product quickly. On content-heavy platforms, it connects users to the exact article, tutorial, or documentation page they need. The greater the relevance, the higher the customer satisfaction and engagement.

Whether you're optimizing a blog, internal tool, or a product catalog, improving relevance directly impacts retention, conversions, and trust.

Let’s explore a real-world example to see how it works in practice.

## What is an example of search relevance?

Let’s take an example of a common e-commerce search query. 

Say someone types ‘wireless headphones’ into a store’s search bar. If the search relevance is good, the top results will bring up popular wireless headphone models like the Sony WH-1000XM5 or AirPods Pro. 

![Example of good search relevance.png](https://unable-actionable-car.media.strapiapp.com/Example_of_good_search_relevance_a1d20f131e.png)

Source: [amazon.com](http://amazon.com) 

If the search relevance is poor, it will bring up headphones with wires as well as other accessories. 

Let’s take another example, of a recipe blog. If you look up ‘vegan pasta’ and get any result besides pasta without meat, dairy, and eggs, then the search relevance is poor. 

![Example of poor search relevance.png](https://unable-actionable-car.media.strapiapp.com/Example_of_poor_search_relevance_e04168322a.png)

Source: [recipesmadeeasy.co.uk](http://recipesmadeeasy.co.uk) 

These examples happen every day, and the difference between a relevant and irrelevant result directly affects user trust, conversions, and retention. 

Businesses that prioritize search relevance improve UX and drive measurable results, such as reduced bounce rates, faster time-to-product, and higher customer satisfaction.

Let’s now look at what affects search relevance behind the scenes.

## What factors influence search relevance?

Here are the factors influencing whether search engines bring up relevant content.

* **Keyword frequency:** This refers to how often the search term appears in a page, which affects the page's ranking. 
* **Natural language processing (NLP) features:** NLP features help search engines understand synonyms, context, and the intent behind a query. For example, it recognizes that ‘cheap laptop’ and ‘budget notebook’ are similar.
* **Personalization:** Search engines can adjust results [based on past user behavior](https://meilisearch.com.cn/blog/personalized-search). Two users with the same query might receive different responses based on location or preference. 
* **Freshness:** Newer content can rank higher, especially for time-sensitive queries. For example, a user searching for a phone with a good camera expects recent results, not results from 10 years ago. 

These are the most common elements that work together to form the foundation of how search systems evaluate and deliver results. 

Next, let’s explore how a search engine calculates and applies relevance in real time.

## How does a search engine determine relevance?

Modern search engines are incredibly clever. 

Thanks to signals such as keyword matches, content structure, document freshness, and link authority, they use ranking algorithms to filter for the best results.

Search engines also apply natural language processing (NLP) and [semantic search](https://meilisearch.com.cn/blog/semantic-search) to understand the intent behind a query rather than just the literal words used.

In more advanced systems, machine learning models refine relevance over time by learning from user behavior, such as clicks, dwell time, and query reformulations. 

These systems don’t just react to input; they also adapt, improving result quality with every interaction. This creates a feedback loop where relevance gets sharper the more the engine is used, helping search systems stay aligned with evolving user intent.

## How is search relevance measured?

Metrics help you evaluate if your search engine provides relevant and useful results to the right users. 

The goal is to quantify whether users are finding what they’re looking for and whether results are being ranked in the correct order.

Here are some of the most commonly used search relevance metrics:

* **Precision** measures how many of the results shown are helpful. Higher precision means fewer off-target results. It keeps things focused so users don’t waste time on the wrong stuff.
* **Recall** checks if your engine found all the good matches. A [high recall score](https://meilisearch.com.cn/blog/mastering-rag) means you're not missing anything important. It's about covering your bases and giving users the whole picture.

![Example of recall and precision.png](https://unable-actionable-car.media.strapiapp.com/Example_of_recall_and_precision_1c6f0efe97.png)

* **Click-through rate (CTR)** tells you how often people click a result after searching. If clicks are low, your top results might not be hitting the mark. It’s a simple way to see if users like what they see.
* **Normalized Discounted Cumulative Gain (nDCG)** is a metric that determines whether relevant results appear high in the results list. A perfect answer won’t help if it’s buried at the bottom. 
* **The F1 score** is a mix of precision and recall. It’s useful when you want to avoid both wrong and missed matches.

Other metrics to consider include the Mean Reciprocal Rank (MRR), Mean Average Precision (MAP), and user satisfaction scores from feedback or surveys.

## What is a relevance score?

A relevance score is a number assigned to each search result that reflects how well the result matches the user’s query. The higher the score, the more relevant the engine considers the result.

Relevance score is calculated during search time – the time it takes to find the relevant search results – by taking into account factors such as keyword frequency, document fields, query intent, and metadata. 

## What are some common challenges in achieving search relevance?

Search relevance isn’t universal: what’s helpful to one user can be completely irrelevant to another. That’s why building a search experience that consistently delivers the right results is both complex and context-dependent.

![What are the common challenges in achieving search relevance.png](https://unable-actionable-car.media.strapiapp.com/What_are_the_common_challenges_in_achieving_search_relevance_374f78bb09.png)

Below are some of the most persistent issues.

### 1. Ambiguous queries

Users often enter short or vague queries like ‘apple’ or ‘terminal,’ leaving the search engine to guess what they really mean. Is it the tech brand or the fruit? An airport terminal or a computer?

Without additional context, such as user history, location, or intent, these queries can return irrelevant or overly broad results. 

Handling ambiguity requires special disambiguation strategies, like query suggestions, autocomplete, or personalized ranking, to guide users toward better results.

### 2. Synonym and variant handling

If someone searches for ‘laptop’ but your site uses ‘notebook’ instead, the match will be lost. The same happens with spelling variants like ‘organization’ and ‘organisation.’ 

Without synonym dictionaries, stemming, and typo handling, users can miss out on content that exists but can’t be found. Good relevance depends on catching those variations every single time.

### 3. Data quality issues

If your data is messy, your search results will be too. Inconsistent tags, missing fields, or duplicate entries confuse the system. 

For example, using the terms ‘color’ and ‘shade’ interchangeably splits the index. 

Clean data, clear fields, and smart indexing rules are the foundation of accurate and relevant search.


### 4. Evolving user behavior

Fast results are one thing, sensible answers are another. The audience wants both. 

[AI-powered search](https://meilisearch.com.cn/blog/ai-powered-search) helps understand what users mean, not just what they type. It looks at intent, learns from behavior, and ranks results more naturally. This creates a smoother experience, especially for platforms with a lot of content or technical depth.

## How can you improve search relevance?

How can we actually improve search relevance? 

We can count on several factors for help. 

For instance, Meilisearch can directly contribute to this by boosting the precision, speed, and usefulness of your search results without all the complex algorithm shenanigans. 

Let’s look at some best practices for optimizing your search engine. We’ll use an example of a Golang-based e-commerce search engine to illustrate.


### 1. Customize Meilisearch ranking rules

Meilisearch relies on ranking rules to bring back the best results. 

How do these work? 

They basically define how your results are prioritized using various parameters, such as word match count, typo count, and field importance. 

You can easily update or reorder these rules to suit your business logic.


```go
client.Index("movies").UpdateRankingRules(&[]string{
  "typo",
  "words",
  "proximity",
  "attribute",
  "exactness",
})
```


This allows you to prioritize matches of specific fields (like `title `over `description`) or emphasize typo tolerance. 

The flexibility to customize these rules means you can fine-tune your relevance algorithm without complex backend engineering. 

Remember, order matters: rules applied earlier have more impact. So, choose wisely!


### 2. Configure synonyms for inclusive matching

You’re most likely wondering what happens if users don’t search for the exact product names. Well, there’s a solution for that as well. 

Meilisearch has a built-in synonym handling feature. It allows you to customize and map similar terms together so ‘product A’ can mean ‘product B’ and vice versa.


```go
client.Index("products").UpdateSynonyms(&map[string][]string{
  "jacket": {"coat", "outerwear"},
  "laptop": {"notebook", "computer"},
})
```


Whether users search for a ‘coat’ or a ‘jacket,’ they’ll see the same results. 


### 3. Tune typo tolerance for better UX

Meilisearch has built-in [typo tolerance](https://meilisearch.com.cn/docs/learn/relevancy/typo_tolerance_calculations), which suits fast typers. By adjusting the typo tolerance level, you can control how forgiving (or unforgiving) the search engine is. 


```go
client.Index("books").UpdateSettings(&meilisearch.Settings{
  TypoTolerance: &meilisearch.TypoTolerance{
    Enabled: meilisearch.Bool(true),
    MinWordSizeForTypos: map[string]int{
      "oneTypo": 5,
      "twoTypos": 9,
    },
  },
})
```


This setting is critical for improving UX. It helps retain users who might otherwise bounce due to zero results caused by simple typing errors.


### 4. Use tokenization and normalization

Meilisearch breaks your text into smaller parts and cleans it up for search. It turns ‘résumé’ into ‘resume’ and ‘Color’ into ‘color.’ Users will still find what they’re looking for, even with slight differences. 

If you’re using Go, this happens in the background. That means better results without extra effort.


### 5. Apply stop words and filtering

Words like ‘the’ or ‘of’ don’t help search. Meilisearch skips them by default, so your engine focuses on the important stuff. 

You can tweak this too:


```go
client.Index("articles").UpdateStopWords(&[]string{"the", "a", "of", "in"})
```


Pair this with [faceted filtering](https://meilisearch.com.cn/blog/nested-hierarchical-facets-guide) for even sharper control. For example, in a product catalog, let users filter by brand, price, or rating. This adds structure to your search and improves user engagement by narrowing results down to exactly what they need.


### 6. Leverage custom ranking for business goals

The default ranking is a good start, but real value comes when your results reflect what matters most to your business. 

Want to show in-stock items first or boost high-rated products? Meilisearch lets you rank results by fields like sales, ratings, or popularity:


```go
client.Index("products").UpdateRankingRules(&[]string{
  "desc(popularity)",
  "typo",
  "words",
})
```


This level of control improves query relevance and links user intent with business metrics. Whether a SaaS site surfaces popular docs or a [marketplace search engine](https://meilisearch.com.cn/blog/marketplace-search-engine) prioritizes trending items, custom ranking ensures your search engine works for you as well as for the user.

Now that you know how to improve search relevance, let’s explore how to test and validate those changes to make sure they work in real-world scenarios.

## How to test search relevance

You can have the smartest ranking rules in the world, but if your search results don’t help users find what they need, it doesn’t matter. 

That’s why testing matters. It shows you whether your search logic aligns with what users expect to see.

Here are a few ways to test how well your relevance holds up.


### 1. A/B testing different configurations

This is a simple way to compare two versions of your search. Maybe one uses more typo tolerance. Maybe the other favors exact matches or gives a boost to specific keywords. 

Run both versions and examine the click-throughs, bounce rates, and conversions. You’ll quickly see which one is more useful to real users.


### 2. Manual relevance grading

This one takes a bit more effort, but it works. Pick a few common queries and review the top results by hand. Are they relevant? Do they make sense? Does the top result actually match what someone is searching for? 

This type of reviewing helps you set a baseline and catch issues that automated testing might miss.


### 3. Collecting user feedback and behavioral data

Don’t be shy. Ask users what they think. Add a quick thumbs up or down. Toss in a ‘Did you find what you were looking for?’ at the end of a search. 

Pair that with user behavior signals like how far people scroll or which results they click. If users always ignore the top result and click the third one instead, it could be a sign that something needs fixing.


### 4. Analyzing search metrics

Metrics like MRR, Precision at K, and nDCG give you a clear picture of how often the right results appear at the top. They help you spot what’s working and what’s falling short. Over time, these numbers guide you toward better performance without guesswork.

Whether you’re building product search, docs lookup, or [site search](https://meilisearch.com.cn/solutions/site-search), testing helps you move from ‘just okay’ to results that make sense to the user. 

## Enhancing search relevance with precision and control

Relevance is what makes search feel intuitive, fast, and useful. Whether you're powering product discovery, technical documentation, or in-app search, delivering relevant results drives user trust, engagement, and conversion, turning search from a utility into a competitive advantage.

What is search relevance: Everything you need to know

On-site search: Definition, implementation, best practices & more

Employees across industries spend countless hours online searching for documents, policies, and answers, only to end up staring at pages and pages of irrelevant search results. 

When internal search doesn’t work, productivity suffers, information is siloed, and morale takes a hit. 

A smart intranet search engine changes that. It delivers fast, relevant answers and helps teams get work done without the digital scavenger hunt.

In this guide, you’ll learn everything you need to know before choosing or building an intranet search system for your organization, including:

* What an intranet search engine does and how it’s different from a typical internal search tool.
* How search engines for intranets work under the hood.
* Key benefits of better intranet search in an organization.
* Common reasons why most intranet searches fall short.
* Features that matter most, including AI-driven personalization and security.
* Top ready-to-use and open-source tools worth exploring.
* Steps to build a custom solution from scratch.
* Optimization tips to improve accuracy, speed, and satisfaction.

## What is an intranet search engine?

An intranet search engine is a tool that helps employees quickly find internal information – whether documents, messages, files, or tools – across a company’s internal systems. Unlike a search engine like Google, which crawls the entire web, intranet search engines focus exclusively on one organization's private data.

In essence, an intranet search engine delivers fast and relevant search results from internal sources. When done right, it transforms how employees access knowledge, saving time and reducing frustration.

Now, let’s see how exactly these systems work.

## How does an intranet search engine work?

At its core, an intranet search engine finds and ranks content stored across a company’s internal systems. 

It does this through a multi-step process:

1. **Crawling:** The search engine scans internal sources – files, folders, wikis, databases, and communication tools – to discover and collect content.
2. **Indexing:** It organizes and stores this content in a searchable index, tagging it with relevant keywords and metadata. Like it’s building a detailed internal map of an organization’s knowledge.
3. **Querying:** When a user enters a search term, the engine checks the query against the index, looking for matching content.
4. **Ranking:** The engine ranks the results based on relevance, using factors like keyword frequency, location, freshness, and context. The goal is to show the most useful results first.
5. **Enhancements (optional):** More advanced systems use Natural Language Processing (NLP) to understand user intent beyond exact keywords. Some also support [federated search](https://meilisearch.com.cn/blog/what-is-federated-search), which pulls results from multiple internal systems into one unified view.

Next, let’s look at how intranet search differs from other types of internal search.

## What is the difference between internal and intranet search engines?

Although the terms intranet and [internal search](https://meilisearch.com.cn/blog/internal-search) are often used interchangeably, their purposes in an organization are very different. 

An intranet search engine provides employees with all the important information from the entire internal digital environment. It helps them access the data they need, no matter where it lives. 

On the other hand, an internal search engine operates within a single platform. Think of the search bar inside your CRM or helpdesk. It works well, but only within that one tool.

Here’s how they compare.

![What is the difference between internal and intranet search engines.png](https://unable-actionable-car.media.strapiapp.com/What_is_the_difference_between_internal_and_intranet_search_engines_d1a1569d3e.png)

Intranet search connects your whole ecosystem. Internal search zooms in on one piece of it.

Let’s break down why that matters for your business.

## Why is intranet search important for organizations?

When employees can’t find what they need, work slows down. Time is wasted, frustration builds, and productivity takes a hit.

An effective intranet search engine flips that script. It makes internal content easily accessible, no matter where it lives, so people can focus on their work, not the hunt.

Here’s what a strong intranet search unlocks:

* **Higher productivity:** Employees stop digging through folders or pinging coworkers for links.
* **Faster decision-making:** Quick access to relevant data leads to smarter, faster choices.
* **Better collaboration:** Teams stay well coordinated when content is easy to find and up to date.
* **Fewer repeated tasks:** Past work is searchable, so employees aren’t constantly starting from scratch.
* **Happier teams:** Less friction means smoother workflows and more time for meaningful work.

When the intranet search works well, everything else becomes easier. 

But building a reliable system starts with understanding its limitations.

## What are the common challenges with intranet search engines?

Sometimes, intranet engines fail. This can be for a number of reasons, including poor implementation, technical limits, or a lack of structure. 

Here are common issues organizations face with intranet search and how to fix them.

### 1. Incomplete indexing

When a search engine fails to index all relevant files, employees miss out on information that could’ve been essential to their role or projects. This usually happens due to improper configuration, limited permissions, or outdated systems. 

A smart search engine, such as [Meilisearch](https://meilisearch.com.cn/), can tackle this by crawling and surfacing content based on real-time changes.

### 2. Irrelevant results

Few things are more frustrating than searching for something specific and getting a wall of noise in return. When search results feel random or off-topic, it’s usually due to poor ranking logic, keyword matching without context, or an engine that doesn't understand user intent.

To fix this, you can use a relevance-focused engine that supports [semantic search](https://meilisearch.com.cn/blog/semantic-search) and contextual ranking.

### 3. Inconsistent tagging and metadata

If your teams aren’t aligned on how they name or tag content, your search engine won’t be either. Imagine one team saving a file as ‘Revenue-Q3-Final’, another calling it ‘Quarterly_Income_July-Sept’, and a third just naming it ‘report123’.

Without a consistent taxonomy and metadata, even a good search engine struggles. The solution is to handle this with customizable filters and flexible schema indexing, so teams can surface the right content even when naming conventions vary.

### 4. Security and permission conflicts

In the case of intranet search engines, there needs to be a balance between access control and usability. An improper setup can expose sensitive organizational data to the wrong individuals. 

Meilisearch supports fine-grained access control and works well with authentication layers, so every employee sees only what they’re supposed to. This keeps both compliance and productivity in check.

Let’s now explore what features truly matter when picking the right intranet search engine.

## What features should you look for in an intranet search engine?

We’ve explained the basic premise of an intranet search engine. But what is the core requirement you must focus on while choosing or building one? 

Let’s have a look below.

![What features should you look for in an  intranet search engine_.png](https://unable-actionable-car.media.strapiapp.com/What_features_should_you_look_for_in_an_intranet_search_engine_5142217683.png)

* **Filters and faceted search:** Helps users narrow down results by department, document type, or date.
* **Natural language support:** Makes search feel intuitive by interpreting everyday phrases rather than just keywords.
* **Typo tolerance:** Users make typing mistakes. Your search tool should still deliver helpful results even with misspellings.
* **Synonym recognition:** Makes sure terms like ‘benefits’ and ‘compensation' or ‘HR’ and ‘People Ops’ lead to the same results.
* **Ranking rules:** Prioritizes high-value content so important information always comes first.
* **Personalization:** Delivers context-aware results by tailoring what’s shown based on department, role, or search history.
* **Access controls:** Ensures users only see content they’re authorized to access, which is key for security and compliance.
* **Speed and scalability:** Results should appear instantly, even with large document volumes or high query traffic.
* **Multi-language support:** Useful for global teams or multilingual workforces needing consistent search experiences across languages.

Now it’s time to look at some of the best out-of-the-box intranet search engine options.


## What are the best out-of-the-box intranet search engines? 

Organizations looking for ready-made intranet search tools have strong options that offer speed, easy integration, and thoroughness. 

**1. Guru**

Guru is a knowledge management platform with an AI-powered intranet search. It connects with Slack, Teams, and internal wikis to give employees fast, verified answers without switching tools.

**2. Coveo**

Coveo delivers smart enterprise search with AI recommendations and analytics. It’s widely used in customer service and knowledge management, with built-in connectors for CRMs and content systems.

**3. Apache Solr**

Apache Solr is a reliable, open-source engine used in many enterprise intranet setups. Its real-time indexing and faceted search capabilities make it ideal for scaling and customizing internal search experiences.

Now, let’s look at the best open-source intranet search engines.

## What are the best open-source intranet search engines? 

When choosing an open-source search engine for your intranet, you want speed and scalability (and maybe customization for advanced users). It should be flexible enough to integrate with your internal systems without requiring a massive DevOps setup.

Here are three of the top picks:

**1. Meilisearch**

Meilisearch wouldn’t be Meilisearch without its lightning-fast performance and developer-friendly setup. Its key features, such as [typo tolerance](https://meilisearch.com.cn/blog/typo-tolerance), semantic search, and ranking rules, make it a prime option in this context, even though it is not specifically built for intranets. 

**2. Typesense**

Typesense is a developer-first alternative that prioritizes simplicity and speed. Its easy-to-deploy architecture and support for real-time updates make it great for teams that want control without the headache of a heavy infrastructure.

**3. OpenSearch**

Forked initially from Elasticsearch, OpenSearch offers top-tier scalability and strong analytics. It’s a fit for enterprises that require a full-text search to go with advanced monitoring, logging, and role-based access. 

Are you looking to build your own intranet search stack? 

Let’s walk through that next.

## How do you create a custom intranet search engine? 

Building your own intranet search engine with Meilisearch gives you complete control and flexibility. You can customize ranking, typo tolerance, and data schema based on your company’s needs. 

Below are clear steps with Go code to get you started:

### 1. Set up Meilisearch and Go client

First things first, let’s start a Meilisearch instance either locally or in a secure cloud environment. 

Then connect from your Go backend using the official SDK:


```go
import "github.com/meilisearch/meilisearch-go"

client := meilisearch.NewClient(meilisearch.ClientConfig{
  Host:   "http://127.0.0.1:7700",
  APIKey: "masterKey",
})
```


This establishes a fast, secure connection for indexing and querying your intranet content.


### 2. Create an index and upload documents

Next, define an index and push your internal documents like PDFs, wiki pages, and support files into Meilisearch:


```go
index := client.Index("intranet_docs")

docs := []map[string]interface{}{
  {"id": "1", "title": "Employee Handbook", "content": "Policies..."},
  {"id": "2", "title": "IT Guide", "content": "Setup instructions..."},
}

task, err := index.AddDocuments(docs)
```


This builds a structured map of your content for typo-tolerant search.


### 3. Configure relevance and search features

Finally, fine-tune the ranking and user experience:


```go
index.UpdateRankingRules(&[]string{
  "typo",
  "words",
  "proximity",
  "attribute",
  "exactness",
})

index.UpdateSynonyms(&map[string][]string{
  "hr": {"human resources"},
})

index.UpdateSettings(&meilisearch.Settings{
  TypoTolerance: &meilisearch.TypoTolerance{Enabled: meilisearch.Bool(true)},
})
```


With these three steps, you’ve built a search engine powered by Meilisearch that’s fast and specific for your intranet.

## How do you choose the right intranet search engine for your needs?

Not all intranet search engines are built the same. Some are plug-and-play. Others give you complete control. The right choice depends on your team’s technical skill, budget, and internal complexity. 

Here’s a quick look at the differences across the three main types: out-of-the-box, open-source, and custom-built intranet search engines.

![How do you choose the right intranet search engine for your needs_.png](https://unable-actionable-car.media.strapiapp.com/How_do_you_choose_the_right_intranet_search_engine_for_your_needs_aeb63c5ee9.png)

Next, we’ll look at how to get the most out of your intranet search engine performance.


## How do you optimize intranet search engine performance?

Even the best intranet search engine needs regular tuning to stay on point. As your organization evolves, so do its data, tools, and user behavior, making room for some much-needed optimization.

Let’s explore some of the most impactful ways to optimize performance:


### 1. Add rich metadata to your content

Metadata helps search engines understand each document's content. It adds context like document type, department, author, or publication date to improve indexing and ranking. When metadata is structured and consistent, users find what they need faster.

Example:


```json
{
  "title": "Employee Benefits 2025",
  "type": "HR Document",
  "author": "Jane Smith",
  "tags": ["benefits", "healthcare", "HR"],
  "department": "Human Resources"
}
```


In Meilisearch, you can include metadata as part of the searchable attributes and use ranking rules to boost results based on priority fields like department or publication date.


### 2. Enable typo tolerance and synonym matching

Employees make mistakes when typing, especially on internal acronyms or jargon-heavy terms. Typo tolerance helps capture near matches, while synonym support enables users to get hits for terms like ‘vacation’ and ‘PTO.’

Meilisearch example:


```bash
curl -X POST 'https://:7700/indexes/docs/settings/synonyms' \
--data '{
  "pto": ["paid time off", "vacation"],
  "hr": ["human resources"]
}'
```


This creates a smoother, more forgiving search experience without requiring perfect spelling or phrasing.


### 3. Keep your content regularly indexed

Outdated or missing records frustrate users. To avoid this, you need to make sure your search engine updates its index frequently to reflect new or edited content. For fast-changing data, set up an automated schedule or trigger-based indexing.

Example script for Meilisearch using Node.js:


```javascript
const { MeiliSearch } = require('meilisearch')

const client = new MeiliSearch({ host: 'https://:7700' })
const index = client.index('documents')

// Assuming newDocuments is your latest content
await index.addDocuments(newDocuments)
```


This keeps search results fresh and relevant as your organization grows.


### 4. Use user behavior to refine results

Analytics can tell you what users are searching for, what they’re clicking on, and where they’re dropping off. That data can help identify gaps in relevance and update synonyms, filters, or ranking rules accordingly.

Insightful metrics to track include:

* Click-through rates on search results
* Queries with no results
* Most common terms per department

Over time, this feedback loop and strategic refinement will significantly improve performance.


### 5. Fine-tune ranking rules

In Meilisearch, ranking rules control how search results are ordered. You can prioritize by freshness, department, popularity, or even metadata tags to guarantee that internal resources always rise to the top.

Sample ranking rule order:


```json
[
  "words",
  "typo",
  "proximity",
  "attribute",
  "exactness",
  "desc(date_published)"
]
```


You can adjust this to reflect how your team searches and what matters most.

## Building a smarter intranet search experience

A powerful intranet search engine unlocks your team’s full potential. When information is buried, scattered, or outdated, frustration sets in and productivity suffers.

The right solution brings clarity to the chaos. It helps employees find the knowledge they need quickly, accurately, and securely so they can focus on meaningful work.

Whether upgrading your current system or building one from scratch, investing in smarter search is one of the most effective ways to boost efficiency across your organization.

We’ve been handed an exciting dream—and it hasn't quite lived up to expectations. 

With the rapid growth of AI, big names like Google promised a revolution in how we discover information. 

Search was meant to become faster, smarter, and more tailored to us. 

Yet, here we are, still wading through unrelated suggestions and one-size-fits-all recommendations. 

Personalized search? Perhaps more like personalized guesswork. 

So, what went wrong? Let’s explore it together. 

## What most "personalized" search experiences actually do

Every rose has its thorn. And so do personalized search engines. 

What’s sold under the sweet sauce of “customization” is often just a simple data retrieval. 

And even then, chances are you won’t get what you’re looking for. 

Why does this happen?

Here are a few reasons:

### Reason #1: Words set in stone

Personalized search engines often follow a hard-coded word order, preconditioning the final results. 

The [Prozis e-commerce company](https://www.prozis.com/) search engine relies on this rule to search for products. 

For instance, if we search for “nut butter for keto diet,” the results are ordered as “hazelnut butter,” “pistachio butter,” and “almond butter.” 

![Prozis e-commerce company search engine.png](https://unable-actionable-car.media.strapiapp.com/Prozis_e_commerce_company_search_engine_b24a69f8dd.png)

Image Source: [Prozis](https://www.prozis.com/)

But here’s the problem.

Hazelnut and pistachio butters, listed as first and second, are not keto-friendly, while almond butter, which actually is ketogenic, comes in third. 

What you see here is relevance ranking. 

The order of words predetermines and prioritizes the search results that closely match the query. 

Yet, something crucial is missing in this case: user intent. 

The next point on our list is about the same issue. 

### Reason #2: All eggs in one basket 

Oftentimes, it’s not the word order that creates stumbling blocks in personalized search. 

It’s an oversimplified user segmentation. 

Personalized search engines often group users into broad categories (e.g., “tech shoppers”, “outdoors enthusiasts”). 

And let’s be honest, it’s easier that way. 

However, the outputs we get are inaccurate and irrelevant recommendations. 

After all, there are nuances in everything. Let’s say two people are outdoor enthusiasts; one loves hiking, but the other hates getting on the trail and prefers luxurious glamping. 

Both belong to the same group. But are they really the same?

Streaming services are guilty of this, and [Netflix](https://www.netflix.com/) is a good example. 

Upon registration, you must choose three movies/TV shows you like. 

![Netflix collecting user preferences.png](https://unable-actionable-car.media.strapiapp.com/Netflix_collecting_user_preferences_3e0362f5b3.png)

Image Source: [Netflix](https://www.netflix.com/)

If you go for a selection of medical shows and series about law and law enforcement, guess what you’ll get. 

![Netflix top pics for you.png](https://unable-actionable-car.media.strapiapp.com/Netflix_top_pics_for_you_ec86072c2b.png)

Image Source: [Netflix](https://www.netflix.com/)

But do these three picks truly reflect *all *of your viewing preferences?

Hardly. 

Yes, you might like some shows about law enforcement, but you might also hate watching *Dexter*—a crime show—because it’s too gruesome. 

That’s not all, though. 

If you look closer at the shows suggested in the image above, you’ll see that some of them have been around for a while (like *House, Prison Break, *or* Suits)*, and you may have seen them already.  

Thus, the Netflix algorithm is also guilty of the filter-bubble effect, meaning you won’t be exposed to anything except what you already engage with.

### Reason #3: Money talks

Personalization implies prioritization. 

In our case, the prioritization of the user’s search intent and their interests. 

Most search engines claim they honor this priority. 

But not before they honor their obligations to the advertisers. 

Many online marketplaces follow this logic, and [AliExpress](https://www.aliexpress.us) is a good example. 

When you search for a product, the platform gives you various options, but not until it shows you two rows worth of paid ads. 

![AliExpress product search.png](https://unable-actionable-car.media.strapiapp.com/Ali_Express_product_search_fef4e07fee.png)

Image Source: [AliExpress](https://www.aliexpress.us)

To be fair, marketplaces like AliExpress need to work with advertisers to sustain their business. 

However, overrunning the search results with ads contradicts AliExpress’s claim about curating “a selection of products tailored specifically to you,” as they claim at the bottom of their homepage. 

You can’t expect a user to be satisfied with product recommendations after scrolling through several rows of ads. 

That’s just not what personalization is about. 

## What is true personalization?

The answer seems simple: personalization is about deeply understanding the user's needs. 

The actual matter is, of course, more complex. 

The biggest obstacle to personalized search is analyzing massive amounts of user data to deliver the most relevant search results. 

Brands and marketplaces heavily rely on AI for this task, but it’s not always the answer. 

After all, AliExpress [uses AI to personalize search results](https://www.alibabacloud.com/blog/alibaba-cloud-ai-search-solution-explained-intelligent-search-driven-by-large-language-models-helping-enterprises-in-digital_601971), but its system is far from perfect. 

AI can be a solid foundation for personalizing search results, but this foundation only maintains its integrity if it stands on the following five pillars. 

### Pillar #1: Intent-based personalization

Personalization happens when the user and the service provider have a complete rapport. 

In our case, the key to building this rapport (since a search engine is a machine) lies in Natural Language Processing, or NLP. 

NLP algorithms use [semantic network models](https://meilisearch.com.cn/blog/semantic-search) to understand user intent, which makes personalization possible.

How does it work?

Essentially, semantic search targets the context behind words and analyzes structured data to understand the semantic meaning of the query. 

Amazon’s A9 search engine is probably the best example of this model in action.

Let’s take the key phrase *book emotional intelligence toddler. *

The keyword here is *toddler*, meaning we are not searching for an emotional intelligence guide for adults. 

The search engine picks up on that and shares exactly what we need: several book options for kids to read. 

![Amazon book search.png](https://unable-actionable-car.media.strapiapp.com/Amazon_book_search_d9ec09968e.png)

Image Source: [Amazon](https://www.amazon.com/)

We also tested our previous peanut butter example, and Amazon’s search engine gave only keto-friendly products as top results. 

![Amazon peanut butter search.png](https://unable-actionable-car.media.strapiapp.com/Amazon_peanut_butter_search_9969618bac.png)

Image Source: [Amazon](https://www.amazon.com/)

But do you still get [personalized recommendations](https://meilisearch.com.cn/blog/personalization-recommendations) if there’s a typo in your query?

Let’s talk about it next. 

### Pillar #2: Typo tolerance

It’s hardly a pleasant experience to have to retype your query simply because you made a typo and got the wrong results. 

Search engines use the [latent semantic indexing method](https://meilisearch.com.cn/blog/latent-semantic-indexing) of information retrieval to minimize such occurrences. 

LSI is robust against typos because it relies on semantic meaning to understand hidden concepts. 

And that’s precisely what you need, especially if you have a wide-range product offering. 

[Minipouce](https://www.minipouce.fr/) is a good example. 

Below, we intentionally made a typo in the word *ring *but still got relevant results. 

![Minipounce typo in search.png](https://unable-actionable-car.media.strapiapp.com/Minipounce_typo_in_search_9add534c79.png)

Image Source: [Minipouce](https://www.minipouce.fr)

Many products in the company’s catalog have similar names, which only increases the chance of making a typo. So Minipouce [used Meilisearch’s open-source version](https://meilisearch.com.cn/blog/minipouce-top-grade-customer-experience) to optimize the product search for relevant results every time. 

### Pillar #3: Real-time adaptive learning

The results for a query should change dynamically during the interaction between the user and the search engine rather than simply relying on static filters. 

Why?

Interaction of any kind is never static.

A user’s preferences and behavior may change while searching for the right product or information, and true personalization must take this into account. 

That’s why it’s essential for a search engine to employ real-time adaptive learning. See how it works in a Meilisearch-powered search engine below.

![dynamic search with AI.gif](https://unable-actionable-car.media.strapiapp.com/dynamic_search_with_AI_b553f2e7b8.gif)

How does it work?

It’s a complex process, but we can break it down to three main steps:

* **Collecting and analyzing user data.** A search engine first collects information on user searches and related interactions to lay the ground for future personalization. 
* **Adjusting the algorithm.** The collected data and its analysis impact the ranking, related searches, and other search algorithm elements to provide the results based on particular intent. 
* **Adapting the results.** As a user further interacts with a search engine, it adapts its behavior to generate and prioritize relevant results to suit the user’s changing preferences. 

Of course, user behavior is not the only factor impacting the relevance of search results. 

The content a search engine is working with also matters. 

Consequently, so does the information retrieval method it uses. 

Let’s talk about it next. 

### Pillar #4: Correct information retrieval method

Information retrieval (IR) refers to the process of finding and retrieving relevant data. 

This process consists of three steps, which you can see below. 

* **Step #1:** Analyzing unstructured data, such as web pages and text documents. 
* **Step #2:** Indexing the data to make it structured, then processing the query to match the index. 
* **Step #3:** Ranking the query results based on relevance. 

![Process behind information retrieval methods.png](https://unable-actionable-car.media.strapiapp.com/Process_behind_information_retrieval_methods_3bdeb3ac9b.png)

You are already familiar with some IR methods, such as LSI mentioned above. 

And, as you may have noticed, they interpret the content a bit differently. 

[Semantic search](https://meilisearch.com.cn/blog/choosing-the-best-model-for-semantic-search) focuses on a query’s intent and contextual meaning, which makes it particularly great for web search. 

LSI is a variation of semantic search that finds hidden concepts in words and documents. Thus, it’s ideal for tasks such as document clustering.  

There’s also [neural search](https://meilisearch.com.cn/blog/neural-search) that employs deep neural networks (DNNs) to understand the context behind a search query. 

Neural search differs from the above methods in its complexity. It explores contextual relations on a more nuanced level, which makes it better for search engines involving conversational queries. 

There is also [hybrid search](https://meilisearch.com.cn/blog/hybrid-search), a blend of all aforementioned models, which is often used in enhanced information retrieval systems. 

What about more real-life uses for each of these IR methods?

Here are some suggestions. 

![Use cases for information retrieval systems.png](https://unable-actionable-car.media.strapiapp.com/Use_cases_for_information_retrieval_systems_df58d9c62f.png)

These are, of course, just a few examples, as IRs can have way more applications. 

But there’s one thing that unites all of them. 

No matter what IR a search engine uses, it deals with personal user data. 

And that calls for privacy concerns. 

Let’s talk about that next. 


### Pillar #5: Respect for privacy

It’s no secret that AI-powered search engines rely on machine learning to provide the most accurate results. 

This, of course, implies that they analyze data from millions of searches and have to examine user data.

But how can you ensure privacy while maintaining the search engine’s ability to provide top-tier personalization?

The following strategies help get this job done. 

* **Data encryption:** protecting the data from third parties by encrypting it at rest and in transit. 
* **Access controls:** introducing multi-factor authentication and role-based permissions. 
* **Limited data sharing:** regulating data sharing with third parties. 
* **Federated learning:** training AI to learn from new system updates instead of raw user data.
* **Effective anonymization:** preventing user de-anonymization by hiding personally identifiable information. 

The key point, of course, is to ask for user permission to use any data they share and, if they change their mind later, to give them complete control over how their information is processed. 

## Build a strong foundation for personalized search

True personalization isn’t just about serving the results that *seem* tailored. 

Most so-called personalized searches fall short because they prioritize static logic, broad segmentation, and advertiser interests instead of user intent. 

But not all is lost. 

Grounding personalization in NLP, using correct information retrieval methods, and, most importantly, respecting privacy are the keys to delivering search experiences that truly matter.

Most personalized search experiences are a lie

What is vector search? Complete guide [2025]

Personalized search is the key to keeping short-attention-span folks interested in your product or service. Users expect results that feel made for them, and personalized search is the key to meeting that expectation — and turning search into a conversion engine.

Here’s what we’ll cover:

* What personalized search means and how it’s different from traditional search.
* How it works behind the scenes: from data collection to result ranking.
* What types of data power it and why they matter.
* Benefits and challenges to consider before implementing it.
* Use cases across industries like e-commerce, streaming, and SaaS.
* Examples in action that demonstrate how personalized search is already everywhere.
* How to implement it using Meilisearch’s high-performance, developer-friendly toolkit.


## What is personalized search?

As the name suggests, personalized search is when search results are tailored to the searchers based on the latter’s unique characteristics, behaviors, and preferences. 

It refers to the search method where your demographics and behavior — past searches, purchases, browsing activity, location, and interests — are used to present the most relevant search results for a search query you initiate.

Unlike traditional search, which delivers the same results to everyone using the same query, personalized search relies on user data to adapt what each person sees in the results. 

You’ve likely seen this in action on platforms like Netflix (suggested titles based on your viewing history), Spotify (custom playlists tailored to your listening history), or Amazon (product recommendations based on your purchasing history).

Today, delivering generic results isn’t just outdated — it’s a missed opportunity. Users expect relevance as the default. 

The better you get at providing it, the more likely they are to click, buy, and stay.

## How does personalized search work?

Personalized search combines behavioral insights and machine learning to make real-time changes to what users see.

![How personalized search works.png](https://unable-actionable-car.media.strapiapp.com/How_personalized_search_works_14ee43ed10.png)

Here’s a high-level look at how [AI-powered personalized search](https://meilisearch.com.cn/blog/ai-powered-search ) works:


### 1. Data collection

The system gathers user-specific signals, such as search history, clicks, the pages users visit, location, and past purchases.


### 2. User modeling

These signals are then used to build a user profile. This user profile could be:

* Session-based (just the current visit)
* Persistent (across different sessions)
* Anonymous or authenticated


### 3. Query handling

Once the user submits a search query, the algorithm interprets it within the context of the user’s profile created in the previous step, adjusting the results based on perceived preferences.


### 4. Ranking & re-ranking

Finally, the system layers personalization on top of relevance scoring. Even if a product matches a keyword exactly, its position can shift depending on what is most relevant *for that user*.

Behind the scenes, features such as collaborative filtering (recommending items based on similar users’ preferences), content-based filtering (suggesting items similar to past content the user has interacted with), and hybrid models determine what rises to the top. Many systems also employ heuristics to facilitate fast decision-making and predict user needs.

Meilisearch supports these processes through its flexible API, which allows the integration of user-specific filters and [vector-based recommendations](https://meilisearch.com.cn/blog/personalization-recommendations ) without compromising on speed, even at scale.


## What data is used in personalized search?

Personalized search can draw from a wide range of data signals. Some are implicit (inferred through behavior) while others are explicit (user-defined preferences).

Here are the common types of data used:

* Search history, like past searches and interactions
* Click, browse, and time-spent-on behavior
* Device type and OS
* Geolocation for localized results
* Time of day/week
* Account information (if logged in)
* Language and filter preferences
* Social signals (likes, shares, follows)
* Interaction with filters, facets, or categories

The richness of your personalization depends on the data you can ethically and transparently collect without violating user trust or data privacy regulations. This user data then informs algorithms to deliver the best results for the highest user satisfaction.


## What is the difference between personalized and traditional search?

The main difference between personalized and traditional search is how results are selected and ranked.

Traditional search relies heavily — or entirely — on matching query terms with indexed content using a static algorithm. Everyone sees the same result for the same input. It’s predictable and uniform, but it's also less relevant.

Personalized search, by contrast, incorporates user data and adjusts results based on the individual user. This provides unique results and improves relevance, but adds complexity, especially around data management, compliance, and UX consistency.

Here’s a quick side-by-side comparison.

![What is the difference between personalized and traditional search_.png](https://unable-actionable-car.media.strapiapp.com/What_is_the_difference_between_personalized_and_traditional_search_b9f818eebf.png)

Personalized search’s reliance on user data introduces variability and complexity. 

Even though it may require more setup, it also returns more value, especially in customer-facing products and services.


## What are the benefits of personalized search?

Personalized search delivers measurable benefits across UX, engagement, revenue, and brand performance.

Here are the key advantages:

* **Higher customer engagement:** Users spend more time interacting with your site or product because of the greater relevance of search results.
* **Boosted revenue:** Relevant suggestions improve click-through rates and sales for most brands.
* **Lower bounce rates:** Users find what they’re looking for faster, so they stay on your site longer.
* **Surfaced niche content:** Personalization helps uncover niche or under-ranked content that users might otherwise miss.
* **Improved retention and loyalty:** A personalized experience builds long-term trust and brand affinity.
* **Better monetization opportunities:** You can highlight relevant high-margin or preferred content/products more effectively.

These benefits drive tangible business outcomes, resulting in a revenue boost of [up to 40%](https://www.mckinsey.com/capabilities/growth-marketing-and-sales/our-insights/the-value-of-getting-personalization-right-or-wrong-is-multiplying) for companies employing personalization. 


## What are the challenges of personalized search?

Personalized search is not without its drawbacks across user data privacy, scalability, and complexity.

![Challenges of personalized search.png](https://unable-actionable-car.media.strapiapp.com/Challenges_of_personalized_search_1b30b4a33b.png)

Implementing personalized search involves hurdles such as:


### 1. Data privacy and compliance

Personalized search often relies on collecting user data, raising GDPR, CCPA, and similar concerns.

Use opt-in consent, clearly communicate the type of data collected, and anonymize or aggregate data wherever possible. Consent management should be baked into your UX from day one.


### 2. Cold start problem

New users or fresh content lack enough data to be included in personalization, taking search back to its traditional state.

You can overcome this by combining contextual signals (e.g., from geolocation or device) with collaborative or content-based filtering. You can also use fallback strategies like popular or trending content to give your personalized search algorithm a foundation.


### 3. Performance and scalability

Real-time re-ranking and personalization at scale are computationally intensive, which raises concerns about costs and scalability.

Use caching, vector databases, or edge computing to maintain speed without sacrificing relevance.


### 4. Over-personalization

Too much personalization can trap users in a ‘filter bubble,’ where they're only shown results they’re likely to agree with, limiting content diversity and discovery.

A good solution for this would be to blend personalized and generic results. For example, use sections like ‘For You’ and ‘Trending Now.’ You could also allow manual user adjustment for a more human-in-the-loop approach.


### 5. Integration complexity

Personalization involves combining multiple data sources, APIs, systems, and service layers, which can be pretty complex.

Choose modular customizable tools like Meilisearch that make it easier to implement personalization in stages for streamlined integration.

Balancing the benefits and drawbacks of personalized search will take you beyond basic search into new realms of possibility.


## What are the use cases for search personalization?

Personalized search has different use cases and applications across various industries. 

![What are the use cases for search personalization_.png](https://unable-actionable-car.media.strapiapp.com/What_are_the_use_cases_for_search_personalization_dbdca13b7e.png)

Some areas where personalized search shines are:


### E-commerce

In e-commerce, personalized search helps users discover what they're likely to purchase. By analyzing previous purchases, browsing history, and the most frequently accessed categories or brands, marketplace search results prioritize items that match users' purchasing habits, thereby predicting their choices.

You can also include price sensitivity and availability to create more relevant, context-based product recommendations.


### Media streaming

Media platforms employ personalization to display content that users are likely to enjoy, based on their viewing history, preferred genres, or browsing behavior. 

For example, the platform could suggest a new period-piece series after the user completes a historical show, or optimize search results to highlight content with familiar actors or directors.

This approach reduces choice fatigue, improves user retention, and helps surface lesser-known but contextually relevant content that might otherwise be buried in extensive catalogs.


### Travel booking

Travel search personalization tailors results by analyzing details from previous searches, favorite spots, airlines, hotel categories, or even loyalty programs. 

For example, if you’re a frequent flyer, you might find business class options at the top of your search results. A returning user could be shown offers for destinations similar to those they’ve visited.


### SaaS platforms

Personalized search in SaaS applications can prioritize the most relevant documentation, feature, or dashboard based on a user's role, past use, or recent activity. 

For instance, developers might first receive content regarding API references, while analytics tools may be the most relevant content for marketers.

Such role-based tailoring speeds up onboarding, reduces support overhead, and enables users to derive value from the product sooner, thereby improving employee engagement and retention.


### Online education

Learning management systems and online learning platforms use personalized search to suggest courses, modules, or learning pathways to students based on their interests, skill levels, and learning history. Whether resuming a suspended course or exploring a new subject, students can use personalization to discover relevant resources, certifications, or subsequent modules.


## What is an example of personalized search?

Let’s bring personalized search use cases to life with some real-world examples.


### 1. ‘Pizza near me’

Let’s say you are searching for good pizza places in your location using the keyword ‘pizza near me.’

Without personalization, a system, such as a food delivery app or Google, will show all registered and available pizza places on the app. 

Limited personalization may result in filtering based on a 5- or 10-mile radius around your location, such as Google’s ‘See results closer to you.’

![Results closer to you Google feature.png](https://unable-actionable-car.media.strapiapp.com/Results_closer_to_you_Google_feature_e9aed062ff.png)

Source: [Google](https://www.google.com/?gl=us)

With actual real-time personalization, the app will show and rank pizzerias you’ve ordered from before, that are open now, and fit your exact delivery radius. 


### 2. Online shopping

Online marketplaces like Amazon and Trendyol aim to offer customers the widest selection of lifestyle products. First visitors will likely receive ‘random’ suggestions, perhaps only personalized to their device type or geolocation.

After a few rounds of online ‘window shopping’ or order placing, the results become more targeted, prioritizing your favorite categories, brands, preferred price range, or products you viewed last time.

![Marketplace product recommendations.png](https://unable-actionable-car.media.strapiapp.com/Marketplace_product_recommendations_b03c36171e.png)

Personalization reduces friction, makes discovery intuitive, and accelerates action in every case. 

But how do you get all this for your system? 

Meilisearch makes it easy!


## How to implement search personalization

Now that we’ve covered the ‘why’ and ‘what,’ let’s look at the ‘how.’

With Meilisearch, real-time search, relevance tuning, and fast indexing enable personalized search through features like filters, [vector search](https://meilisearch.com.cn/blog/what-is-vector-search), and multi-tenancy.

Here’s how to approach it:


### With localized content

Personalized search with localized content uses geosearch or filters to prioritize results based on user location, language, or locale. 

Meilisearch’s [sorting features](https://meilisearch.com.cn/docs/learn/filtering_and_sorting/sort_search_results) and [geospatial search capabilities](https://meilisearch.com.cn/docs/learn/filtering_and_sorting/geosearch) enable this.

For example, to sort correctly indexed restaurants based on their proximity to the Eiffel Tower, the following Python script for the `_geoPoint` sorting function may come in handy:


```python
client.index('restaurants').search('', {
  'sort': ['_geoPoint(48.8561446,2.2978204):asc', 'rating:desc']
})
```


For documents to be correctly sorted based on their geographic location, ensure they contain a valid `_geo` field.


### With recent searches

Perhaps the most widely used personalization criterion is the user’s past searches. Using the user’s recent activity in the search system, the application can suggest and provide the most relevant results. 


## Bringing it all together: personalized search for real impact

Personalized search is no longer a ‘nice-to-have’; it’s a competitive necessity.

It transforms users' interactions with and feelings about your platform by delivering natural, effortless, and uniquely relevant search results. 

The result? Higher engagement, better retention, and stronger conversion metrics.


Personalized search: Deliver ultra-relevant results that convert

Firebase is a BaaS (Backend as a Service) platform. One of its backend services is the Cloud Firestore, which allows you to perform full-text search using a third-party extension.

Firebase users can query document collections in Cloud Firestore with a set of functions available in SDKs for several programming languages, including Swift, Kotlin, Python, Java, PHP, Ruby, and more.

Cloud Firestore does not provide native indexing, so users must use third-party services for document indexing and performing AI-powered searches.

This tutorial will guide you through the steps to index documents from Cloud Firestore using the [Meilisearch extension](https://extensions.dev/extensions/meilisearch/firestore-meilisearch).

## 1. Deploy Meilisearch

You first need to have Meilisearch running on a cloud service. You can either self-host it or use [Meilisearch Cloud](https://meilisearch.com.cn/cloud) for an easier setup.

![image5.png](https://unable-actionable-car.media.strapiapp.com/image5_15f2d9cbbd.png)

This step is required because Meilisearch will provide the indexation of Firebase documents and search capabilities. Meilisearch utilizes machine learning (ML) models to convert documents (JSON files) into vector embeddings, which are stored in a vector space for fast and real-time database retrieval.

To install Meilisearch locally, you can run the following cURL command:


```sh
# Install Meilisearch
curl -L https://install.meilisearch.com | sh
```


Then you need to run Meilisearch:


```sh
# Launch Meilisearch
./meilisearch --master-key="aSampleMasterKey"
```


Let’s now see how to create a Firebase project connected to Meilisearch using the [Meilisearch extension](https://extensions.dev/extensions/meilisearch/firestore-meilisearch).

## 2. Create a Firebase project

Note: You can skip this step if you already have a Firebase Project with a Firebase database containing your documents.

Once you have Meilisearch up and running, you can create a Firebase project, configure it, and add a Firestore database.

There are several ways to configure a project on Firebase. You can do it directly on the [Firebase Console](https://console.firebase.google.com/) or use the [API](https://firebase.google.com/docs/projects/api/workflow_set-up-and-manage-project).

![image23.png](https://unable-actionable-car.media.strapiapp.com/image23_2100dd9bbe.png)

On the console, your project’s page looks like this:

![image24.png](https://unable-actionable-car.media.strapiapp.com/image24_3e3f17f124.png)

On the left side, click ‘Build’ and choose ‘Firestore Database.’

![image3.png](https://unable-actionable-car.media.strapiapp.com/image3_1976cbbf78.png)

From there, you can start adding documents to your new database.

![image6.png](https://unable-actionable-car.media.strapiapp.com/image6_5297a42b83.png)

Now let’s see how to connect [firestore-meilisearch](https://github.com/meilisearch/firestore-meilisearch) to Cloud Firestore.

## 3. Install Meilisearch’s Firebase extension

If you look at the extensions in your Firestore Cloud page, you won’t find Meilisearch as a default. Therefore, you need to install it from the [Firebase Extensions Hub](https://extensions.dev/extensions/meilisearch/firestore-meilisearch).

![image14.png](https://unable-actionable-car.media.strapiapp.com/image14_579572e53f.png)

You need to activate the [Blaze pricing plan to add this and other extensions](https://firebase.google.com/pricing?authuser=0). You will be charged a small amount (typically around $0.01/month) for the Firebase resources required by this extension, even if it is not used.

![image17.png](https://unable-actionable-car.media.strapiapp.com/image17_27fac8457a.png)

If you don’t have a billing account, you can quickly create one in the [Google Cloud Console](https://cloud.google.com/billing/docs/how-to/manage-billing-account). Once done, you can activate the extension and set up a budget amount.

![image20.png](https://unable-actionable-car.media.strapiapp.com/image20_33bc9c5dec.png)

The billing account is successfully connected to the Blaze pricing plan with these steps.

The next step to activate the [firestore-meilisearch](https://github.com/meilisearch/firestore-meilisearch) extension is to review the APIs in your Firebase project. If you don’t have the required ones enabled, you’ll be asked to activate them.

![image11.png](https://unable-actionable-car.media.strapiapp.com/image11_60c2a351ea.png)

After enabling the APIs, you’ll be granted a service account. Finally, you’ll be asked to configure the extension, which includes setting a location, a collection path, the fields to index, and the Meilisearch index name, host, and key (optionally). 

In the following example, we created a collection for movies:

![image1.png](https://unable-actionable-car.media.strapiapp.com/image1_2882d97b25.png)

You’re now ready to install the extension, which takes between three and five minutes.

![image21.png](https://unable-actionable-car.media.strapiapp.com/image21_f8058db5af.png)

Once installed, you can test Meilisearch, but first, you need to check if you have a collection in your Firebase project with the same name as the one configured in the extension.

![image2.png](https://unable-actionable-car.media.strapiapp.com/image2_c13c720cbe.png)

If not, you can visit the [project’s dashboard](https://console.firebase.google.com/) and add your collection accordingly.

![image19.png](https://unable-actionable-car.media.strapiapp.com/image19_2925f03110.png)

This is the data we are using in our example:

title: The Hobbit: An Unexpected Journey

poster &lt;[https://image.tmdb.org/t/p/w500/yHA9Fc37VmpUA5UncTxxo3rTGVA.jpg](https://image.tmdb.org/t/p/w500/yHA9Fc37VmpUA5UncTxxo3rTGVA.jpg)>

overview: Bilbo Baggins, a hobbit enjoying his quiet life, is swept into an epic quest by Gandalf the Grey and thirteen dwarves who seek to reclaim their mountain home from Smaug, the dragon.

release_date: 1353888000

Once you have added this movie, you should be able to see it when accessing Meilisearch’s search preview:

![image7.png](https://unable-actionable-car.media.strapiapp.com/image7_db9ecdd0ae.png)

Well done! You have successfully installed the Meilisearch Firestore extension!

When you add, update, and delete documents from your Firestore collection, they will be mirrored in Meilisearch.


### Managing your extension

To access the overview panel of the extension, first click on the ‘Extensions’ tab on Firebase’s sidebar menu, then find the Meilisearch extension and click on ‘Manage.’ Finally, click on ‘Extension configuration’ and you can now change the collection, host, index, and so on.

![image13.png](https://unable-actionable-car.media.strapiapp.com/image13_7ac6468575.png)

Accessing your logs allows you to monitor your cloud functions and obtain different levels of information. You may access an extension’s logs via the ‘Extensions’ tab. Alternatively, you can also visit the ‘Functions’ tab and select ‘Logs,’ as indicated in the image below.

![image10.png](https://unable-actionable-car.media.strapiapp.com/image10_a35bee898c.png)

## 4. Set up a search interface

In the previous chapter, we successfully installed and configured the Meilisearch extension on Firestore. Now it’s time to query data using a simple search engine application. Here we will see how to create a search bar for your project using this [GitHub repository](https://github.com/meilisearch/meilisearch-js-plugins/tree/main/packages/instant-meilisearch).


### Populating your Firestore collection with data

The first step is to add more documents to our Firestore database. In our case, we will use this [collection of movies](https://meilisearch.com.cn/movies.json). Refer to the Firebase documentation for more information on adding and managing [data](https://github.com/meilisearch/firestore-meilisearch).

Once you have finished adding content to your Firestore database, visit your Meilisearch search preview to check that Meilisearch has successfully indexed your documents.

![image12.png](https://unable-actionable-car.media.strapiapp.com/image12_92dfdaf356.png)

### Search in your document

Now let's create a great search experience. There are many ways to do this, but we’ll keep it simple this time and use [instant-meilisearch](https://github.com/meilisearch/meilisearch-js-plugins/tree/main/packages/instant-meilisearch), our plugin for the instant-search JavaScript library.

Create an index.html file in your preferred development environment. This HTML page should contain a search bar and a box to contain the returned search results:


```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Meilisearch demo</title>
    <link rel="stylesheet" href="<https://cdn.jsdelivr.net.cn/npm/instantsearch.css/themes/algolia-min.css>" />
</head>
<body>
    <div>
        <div id="searchbox"></div>
        <div id="hits"></div>
      </div>
  
      <script src="<https://cdn.jsdelivr.net.cn/npm/@meilisearch/instant-meilisearch/dist/instant-meilisearch.umd.min.js>"></script>
      <script src="<https://cdn.jsdelivr.net.cn/npm/instantsearch.js@4>"></script>
      <script>
          const searchClient = instantMeiliSearch(
              'your Meilisearch url',
              'your Meilisearch API key'
            )
            const search = instantsearch({
              indexName: 'movies',
              searchClient
            })

            search.addWidgets([
              instantsearch.widgets.searchBox({
                container: '#searchbox',
              }),
              instantsearch.widgets.hits({
                container: '#hits',
                templates: {
                  item: `
                    <div style="text-align:center;">
                      <div class="hit-name">
                        {{#helpers.highlight}}{ "attribute": "title" }{{/helpers.highlight}}
                      </div>
                      </br>
                      <div>
                        <img src="{{poster}}" width="200px" />
                      </div>
                    </div>
                  `,
                },
              }),
            ])

            search.start()
      </script>
</body>
</html>

```


Remember to replace the example’s configuration with your own dataset. This might include the indexName if you named your index something other than ‘movies,’ your instance’s URL, and your API authentication token.

If everything went well, you should be able to access your index.html file and start searching right away:

![image15.png](https://unable-actionable-car.media.strapiapp.com/image15_80c0be763b.png)

Congrats! You have added full-text search capability to your Cloud Firestore. Your Firebase collection and your Meilisearch index will automatically stay in sync as long as the firestore-meilisearch extension is installed.


## How is Firebase search used?

Firebase offers full-text search capabilities on indexed fields through third-party solutions. Common use cases include:


* **User profiles**: Filtering users by name or email.
* **Product catalogs**: Searching items by category or price.
* **Blog posts**: Finding articles by title or tags.
* **Geolocation**: Querying places using geo data.


### Does Firebase have vector search?

No. Firebase lacks a built-in [vector search](https://meilisearch.com.cn/blog/introducing-vector-search) for semantic or AI-powered queries. However, the Meilisearch [extension](https://extensions.dev/extensions/meilisearch/firestore-meilisearch) enables vector search by indexing Firestore documents, allowing similarity-based searches.


### Does Firebase support full-text search?

No. Firebase only supports exact string matching. For features like typo-tolerance, synonyms, or ranked results, the Meilisearch [extension](https://extensions.dev/extensions/meilisearch/firestore-meilisearch) indexes Firestore data to deliver fast, flexible full-text search.


## Enable reliable search in your Firebase app with Meilisearch

Adding search to your Firebase app doesn’t have to be a complex process. In fact, you can give users fast, accurate results with the proper setup. 

The key is to start simple, scale smart, and use Meilisearch.

How to implement search in Firebase

Imagine you're building a blog in Rails, and your users keep misspelling post titles in the search bar, only to find no results. Frustrating, right? 

What if your Rails app or website had a search feature that’s lightning-fast *and *smart enough to handle typos?

Meilisearch is your answer. It's a lightweight, typo-tolerant, and lightning-fast search engine that offers a seamless developer experience and out-of-the-box relevancy tuning.

You can make a search engine with Ruby on Rails in Meilisearch by:

1. Setting up Meilisearch and installing dependencies.
2. Configuring Meilisearch in the Rails app.
3. Defining a model and enabling Meilisearch indexing.
4. Populating and indexing data.
5. Implementing a backend and frontend.
6. Customizing settings.

A Ruby on Rails–powered search engine can be used for building e-commerce platforms, blogs, or searchable knowledge bases. Regardless of your use case, a search engine built with Ruby on Rails in Meilisearch comes with a slick search interface that’s both powerful and user-friendly.

## 1. Set up Meilisearch and install dependencies

First, we need to get Meilisearch up and running and integrate it with our Rails app. This will lay the foundation for your search engine.

Meilisearch is open source and free if you choose to [host it locally](https://meilisearch.com.cn/docs/learn/self_hosted/getting_started_with_self_hosted_meilisearch). Or, you can choose Meilisearch Cloud for a fully managed hosting experience, with no need to handle infrastructure or updates yourself. 

For this tutorial, we’ll use a local instance, which is perfect for testing. You’ll need Ruby 3.0+ and Rails 6.1+ to ensure compatibility. Older versions may still allow it to function, but they are not officially supported.

The `meilisearch-rails` gem simplifies the integration, handling indexing and syncing with your database. Let’s install Meilisearch and add the gem to your project.

To install Meilisearch locally, follow the instructions in the official [Meilisearch documentation on GitHub](https://github.com/meilisearch/meilisearch-rails). You can download the binary and run it with a simple command. Once running, Meilisearch is accessible at [http://127.0.0.1:3000](http://127.0.0.1:3000).

Open your `Gemfile `and, with `gem` in the command line, add:


```ruby
gem install meilisearch-rails

source 'https://rubygems.org.cn'

gem 'meilisearch-rails'
```


Run `bundle install` to install the gem. If you hit any issues, double-check your Ruby and Rails versions, as the gem requires recent versions for full compatibility.

With Meilisearch and the gem installed, we’re ready to configure our Rails app to connect to it.


## 2. Configure Meilisearch in your Rails app

Now, let’s configure our Rails app to connect to Meilisearch. Think of this step as setting the coordinates that guide your app to the search engine.

Create a new configuration file to specify the `MEILISEARCH_HOST `and `MEILISEARCH_API_KEY`. This ensures smooth and secure communication between your app and Meilisearch. 

In development, you can skip the API key, but in production, it’s essential for maximum security. Proper configuration, such as what we’re doing now, prevents connection errors and ensures smooth indexing and searching.

Create a new file at `config/initializers/meilisearch.rb`:


```ruby
Meilisearch::Rails.configuration = {
  meilisearch_url: ENV.fetch('MEILISEARCH_HOST', 'https://:7700'),
  meilisearch_api_key: ENV.fetch('MEILISEARCH_API_KEY', 'YourMeilisearchAPIKey')
}
```


If you’re using Meilisearch Cloud, replace the URL with your cloud instance’s address, which is available after signing up for Meilisearch Cloud. For local development, the default URL works fine. If you encounter connection issues, ensure Meilisearch is running and the URL is correct.

Now that our app knows where to find Meilisearch, let’s set up a model to index data.


## 3. Define a model and enable Meilisearch indexing

This step is where the magic starts: we’ll make our data searchable by indexing it with Meilisearch. Indexing means cataloging your information and data so Meilisearch can quickly find matches during user searches.

For this example, we’ll use the hypothetical Rails model `Article` and include the `MeiliSearch::Rails` module to enable automatic indexing. You’ll decide which attributes to index, like `title `and `body`, and configure how they’re used in searches. Meilisearch syncs with your database via `ActiveRecord `callbacks, so you don’t have to worry about updating it manually.

First, generate a model if you don’t have one:


```ruby
rails generate model Article title:string body:text category:string
rails db:migrate
```


Then, open `app/models/article.rb` and add:


```ruby
class Article < ApplicationRecord
  include MeiliSearch::Rails

  meilisearch do
    attribute :title, :body, :category
    searchable_attributes [:title, :body]
    filterable_attributes [:category]
    sortable_attributes [:created_at]
  end
end
```


Here’s what’s happening:

* `attribute` lists the fields requiring indexing.
* `searchable_attributes` are fields users can search.
* `filterable_attributes` allow filtering of the results, e.g., by category.
* `sortable_attributes `enable sorting, e.g., by creation date.

Here, choosing the right attributes is crucial. For example, indexing `title` and `body` makes sense for a blog, but you might want to add `tags` or `author` depending on your use case. Choose only the most relevant fields to index for better performance and faster search results.

With our model ready, let’s add some data to the index.


## 4. Populate and index sample data

To test our search engine, we need data to search through. For this purpose, we will populate our database with sample articles.

Using a seed file, we’ll create sample records that Meilisearch will automatically index. This will let you see how Meilisearch handles real data and prepare you for testing search queries. Meilisearch’s efficiency really shines here, as it can index thousands of records at lightning speeds.

To start, create or update `db/seeds.rb` with the articles you want searched:


```ruby
# Clear existing articles — use only in development or testing!
Article.destroy_all
articles = [
  { title: "Ruby on Rails Basics", body: "Learn the fundamentals of Rails.", category: "Beginner" },
  { title: "Advanced Rails Techniques", body: "Dive into complex Rails features.", category: "Advanced" },
  { title: "Rails Performance Tips", body: "Optimize your Rails app.", category: "Performance" },
  { title: "Building APIs with Rails", body: "Create robust APIs in Rails.", category: "API" },
  { title: "Rails Security Best Practices", body: "Secure your Rails application.", category: "Security" }
]
articles.each { |article| Article.create!(article) }
puts "Articles seeded!"
```


Then, run:


```ruby
rails db:seed
```


Meilisearch will index these records automatically using the aforementioned `ActiveRecord `callbacks. To verify, you can use Meilisearch’s API or dashboard to check the `articles `index. If (correct) data isn’t appearing, ensure your Meilisearch instance is running and the configuration is correct.

Now, things get even more interesting — it’s time to implement the search functionality.

</Callout>


## 5. Implement backend search functionality

First, we’ll create a controller to handle search queries and display accurate results.

This step sets up a `SearchController `to process user input and fetch results from Meilisearch. The `meilisearch-rails` gem makes this easy by providing a `search `method that returns `ActiveRecord `objects, so you can treat results like regular model instances. Additionally, Meilisearch’s typo tolerance ensures users get relevant results even with misspellings.

Create `app/controllers/search_controller.rb`:


```ruby
class SearchController < ApplicationController
  def index
    @query = params[:q]
    @results = Article.search(@query) if @query.present?
  end
end
```


Update your routes in `config/routes.rb`:


```ruby
Rails.application.routes.draw do
  get 'search', to: 'search#index'
end
```


Create a view at `app/views/search/index.html.erb`:


```erb
<h1>Search Articles</h1>
<%= form_with url: search_path, method: :get, local: true do %>
  <%= text_field_tag :q, params[:q], placeholder: "Search articles..." %>
  <%= submit_tag "Search" %>
<% end %>

<% if @results %>
  <h2>Results for "<%= @query %>"</h2>
  <ul>
    <% @results.each do |result| %>
      <li><strong><%= result.title %></strong>: <%= result.body %></li>
    <% end %>
  </ul>
<% end %>
```


Visit [https://:3000/search](https://:3000/search) and try queries like ‘Ralis’ (a typo for ‘Rails’). Meilisearch’s typo tolerance will still return relevant results, as expected. If results aren’t appearing at all, or they seem to be incorrect, check your model’s indexing settings or Meilisearch logs.

Now, let’s take it up a notch with a frontend search interface through our [JavaScript API Client](https://github.com/meilisearch/meilisearch-js/) or [Instant Meilisearch plugin](https://github.com/meilisearch/instant-meilisearch).


## 6. Add a frontend search with instant Meilisearch

For a search-as-you-type experience, we’ll integrate Meilisearch’s simple frontend interface using `instant-meilisearch`.

This step enables dynamic, instant search functionality in your app, giving users an interactive experience as they type. Meilisearch’s impressive response speed — with response times ≤50ms — ensures results appear almost instantly. We’ll use a simple JavaScript setup, but you can extend it with [frameworks like React](https://meilisearch.com.cn/with/react) for a polished UI.

Install the library via `npm `(or `yarn`). Note: this assumes your Rails app is already set up with a JavaScript bundler such as Webpacker or Importmaps.


```
npm install @meilisearch/instant-meilisearch
```


Create `app/javascript/search.js`:


```js
import { instantMeiliSearch } from '@meilisearch/instant-meilisearch';

const searchClient = instantMeiliSearch(
  '',// URL of Meilisearch instance
  '' // Meilisearch API key
);

const search = async (query) => {
  const response = await searchClient.search([{
    indexName: 'articles',
    query
  }]);
  const resultsDiv = document.getElementById('results');
  resultsDiv.innerHTML = response.hits.map(hit => `<div>${hit.title}: ${hit.body}</div>`).join('');
};

document.getElementById('search-input').addEventListener('input', (e) => {
  search(e.target.value);
});
```


Update `app/views/search/index.html.erb`:


```erb
<h1>Search Articles</h1>
<input type="text" id="search-input" placeholder="Search articles...">
<div id="results"></div>
```


As before, test the search at [https://:3000/search](https://:3000/search). Typing ‘Rail’ should show results instantly.

Next, let’s explore our customization options.


## 7. Customize Meilisearch settings

To make your search engine even better, you can tweak Meilisearch’s settings to fit your product’s needs.

Meilisearch allows you to customize ranking rules, synonyms, and stop words to improve search relevance. For example, you might want ‘Rails’ and ‘Ruby on Rails’ to be treated as synonyms, or prioritize results based on recency.

For instance, here is how to adjust ranking rules to prioritize certain fields:


```ruby
Article.meilisearch_index.update_settings({
  rankingRules: [
    "words",
    "typo",
    "proximity",
    "attribute",
    "sort",
    "exactness",
    "created_at:desc"
  ]
})
```


These settings ensure newer articles rank higher. Feel free to play around and test different configurations to see what works best for your users.

Finally, let’s ensure your search index stays in sync with your database for the most accurate results.


## 8. Handle updates and deletions

The `meilisearch-rails` gem automatically handles indexing when you create or update records. However, it’s still worth understanding how to manage updates and deletions yourself, especially if you’re building more complex web applications. This will ensure your search results always reflect the latest data and avoid stale or missing entries.

To manually delete a record from your index:


```ruby
article = Article.find(1)
article.remove_from_index!
Article.destroy! # Removes from Meilisearch index
```


If you need to reindex all records, for example, after changing any indexed attributes, run:


```
Article.reindex!
```


To clear your index entirely, use:


```
Article.clear_index!
```


Be cautious with reindexing large datasets, however, as it can be resource-intensive. In production environments, you can schedule such tasks during low-traffic periods.


## Can I make a search engine with Ruby on Rails for free?

Yes, you can build a search engine with Ruby on Rails and Meilisearch at no cost for development and small-scale production.

Meilisearch’s open-source version is free to self-host on your own servers or local machine, and the `meilisearch-rails` gem has no licensing fees. For development, this is ideal, as you only need a server to run Meilisearch. 

For production, however, hosting costs depend on your infrastructure. Small apps can run on affordable servers, while the costs may skyrocket for larger projects.

Meilisearch Cloud offers a 14-day free trial without requiring a credit card, making it perfect for testing. Post-trial, pricing scales with usage (documents and search requests), starting with the Build plan for small businesses at $30/month.

Let’s compare Meilisearch to other open-source search engines.

## What are the best open-source search engines for Ruby on Rails?

Open-source search engines provide powerful, license-free solutions for adding search to Rails apps. Here are the top options:

* **Meilisearch**: Known for its speed (under 50ms) and simplicity, Meilisearch integrates seamlessly with Rails via the `meilisearch-rails` gem. It’s ideal for small to medium apps, offering [typo-tolerance](https://meilisearch.com.cn/blog/typo-tolerance) and search-as-you-type features. Its lightweight nature makes it easy to set up and maintain yourself, while also providing a hosted option for a maintenance-free experience.
* **Elasticsearch**: A robust engine, Elasticsearch excels in handling large datasets and complex queries. Gems like Searchkick simplify integration. It’s perfect for enterprise apps but requires more resources and setup than Meilisearch.
* **Solr**: Solr offers advanced functionalities like full-text search and faceting. The Sunspot gem provides Rails integration. It’s highly configurable, which can get complex for smaller projects.
* **Typesense**: A lightweight alternative for creating search engines for Ruby on Rails, Typesense offers fast, typo-tolerant search. While it lacks a dedicated Rails gem, its API is easy to use for simple setups.

Now, let’s look at other languages for building search engines.


## What programming languages besides Ruby are used to build search engines?

Aside from Ruby, several programming languages are well-suited for building search engines, each with its unique strengths. Some common languages you can use to build search engines are:


* **JavaScript**: Using Node.js, you can build server-side search with libraries like Lunr or integrations with Meilisearch. JavaScript’s asynchronous nature is great for real-time search. Learn how to [build a search engine in JavaScript](https://meilisearch.com.cn/blog/javascript-search-engine).
* **PHP**:Frameworks like Laravel use Scout to integrate with Meilisearch, making PHP a solid choice for web apps that include search engines. Learn how to [build a search engine in PHP](https://meilisearch.com.cn/blog/php-search-engine).
* **Golang**: Golang’s performance and concurrency make it ideal for high-speed search engines. Libraries like Bleve support full-text search, further increasing its applicability. Learn how to [build a search engine with Golang](https://meilisearch.com.cn/blog/golang-search-engine).

## Creating a search engine in Ruby on Rails made simple

Building a search engine with Ruby on Rails and Meilisearch is easier than you’d think. Set up Meilisearch, index data, add a backend and frontend, and customize the settings to your heart’s content. Meilisearch’s speed, typo-tolerance, and seamless Rails integration make it a top choice for developers looking for fast search engine configuration.
