In today’s digital age, efficient search functionality is crucial for delivering a seamless user experience. Whether you’re building an e-commerce platform, content management system, or any application requiring search, having a robust and fast search engine can make all the difference. One such powerful and open-source search engine is MeiliSearch.

In this guide, we will delve into the features and benefits of MeiliSearch, along with hands-on examples in TypeScript to help you integrate it into your projects.

What is MeiliSearch?

MeiliSearch is a fast, open-source, and feature-rich search engine that’s designed to be both easy to set up and highly customizable. It’s built with performance in mind, ensuring lightning-fast search results for both small and large datasets.

MeiliSearch also provides a simple and intuitive API, making it a great choice for developers looking to enhance search capabilities without the hassle of extensive configuration.

Key Features

1. Fast and Relevant Results

MeiliSearch employs advanced ranking algorithms that deliver accurate and relevant search results, even for complex queries. This is achieved through features like typo-tolerance and synonym handling, which ensure that users find what they’re looking for, even if they make spelling mistakes or use synonyms.

2. Real-Time Indexing

One of MeiliSearch’s standout features is its real-time indexing. As soon as new data is added or updated, the search index is updated in real-time, ensuring that users always have access to the most up-to-date information.

3. Full-Text Search

MeiliSearch supports full-text search, which means it can search for keywords and phrases across the entire content of indexed documents. This is perfect for applications that need to search within large bodies of text.

4. Customizable Ranking

Developers can fine-tune the ranking criteria to tailor search results to specific needs. This helps prioritize certain attributes or documents, providing control over the user experience.

5. Easy Integration

With its simple API and extensive documentation, MeiliSearch is easy to integrate into TypeScript, Python, PHP, Java, Ruby, Go, C#, Rust, Swift and Dart.

Getting Started

Let’s dive into the process of integrating MeiliSearch into your TypeScript application with some practical examples.

Installation

You can install MeiliSearch using npm (Node Package Manager):

npm install meilisearch

Setting Up MeiliSearch

To set up MeiliSearch, you’ll need to import the package and initialize the MeiliSearch client:

import { MeiliSearch } from 'meilisearch';

const client = new MeiliSearch({
  host: 'http://localhost:7700', // Replace with your MeiliSearch server URL
});

Indexing Data

Let’s assume you have a collection of documents to index. For instance, let’s index a list of books:

const books = [
  { id: 1, title: 'The Great Gatsby', author: 'F. Scott Fitzgerald' },
  { id: 2, title: 'To Kill a Mockingbird', author: 'Harper Lee' },
  // Add more books here
];

const index = client.index('books'); // Create an index named 'books'

(async () => {
  await index.addDocuments(books); // Index the list of books
})();

Performing Searches

Searching with MeiliSearch is a piece of cake!

(async () => {
  const searchResults = await index.search('mockingbird'); // Search for 'mockingbird'
  console.log(searchResults.hits); // Array of search results
})();

Custom Ranking

You can customize the ranking to influence the order of search results:

const customRankingRules = [
  'asc(title)', // Rank by title in ascending order
  'desc(author)', // Rank by author in descending order
];

(async () => {
  const searchResults = await index.search('kill', {
    customRanking: customRankingRules,
  });
  console.log(searchResults.hits);
})();
