What is Magento 2 Elasticsearch?

Elasticsearch is an open and distributed search and analytics engine. It covers various data types, including textual, numerical, geospatial, structured, and unstructured. Powered by Apache Lucene, an open-source full-text search library, it functions as a full-text search solution. It offers related keywords and complete queries based on the input.


Elasticsearch also enables store-wide search capabilities. It includes suggesting related products, images, prices, ratings, etc, to refine search results.


Starting with Magento 2.4 version, Elasticsearch is the default catalog search engine in Adobe Commerce. It's essential to Magento installations and can be disabled if needed. It significantly improves the customer experience by providing faster and more relevant search results. It also enhances the conversion rate with seamless shopping experiences.

How does Elasticsearch work?

Elasticsearch uses its indexing feature to provide fast and reliable search results. These indices are like organized collections of documents. It makes it easier to retrieve data quickly and store related documents together.


When Elasticsearch receives raw data from various sources, such as logs, system metrics, and web applications, it processes and indexes it. The indexing allows users to perform detailed searches on the data. It also helps them get detailed summaries of their information through aggregations.

Benefits of Elasticsearch For Your Magento Store

1. Enhanced Search Capabilities

Enhanced search plays a crucial role in minimizing bounce rates. Elasticsearch facilitates swift result generation and real-time relevant outcomes. Features like auto-completion and auto-suggestion save customers time and effort while reducing incorrect queries.

Elasticsearch efficiently handles typographical errors or misspellings, a common issue for search engines. It detects stop words and their corresponding phrases, ensuring the provision of accurate and related search results.

2. Quick Search

Elasticsearch is a powerful tool capable of retrieving searched keywords in under 10 seconds. It is significantly faster than traditional SQL-based searches. It uses Lucene and distributed inverted indices for a full-text search.

Elasticsearch speeds up future searches by storing search queries in a cache. It uses cached filters to do this, shortening the time it takes for a document to become searchable. The tool makes Magento search results faster and more responsive.

3. Scalability and Data Management

Elasticsearch is designed with a distributed structure. It stores documents across different parts called "shards.” It adds redundancy in case hardware fails. This setup lets it scale easily to many servers and handle large amounts of data efficiently.

It can work smoothly across different clusters or systems with many nodes. When moving from a smaller cluster to a larger one, minimal preparation is required, making the transition nearly seamless.

4. Data handling

Elasticsearch relies on JSON (JavaScript Object Notation) for its data handling. It stores data in JSON documents, allowing it to understand the data structure and perform searches. This approach means you don't need to define the data structure in advance.

Elasticsearch usually uses default settings for indexing unless you specify a specific data type. If you index an object with a new property later, Elasticsearch updates its mapping definitions automatically. This adaptability eliminates the need for predefined schemas.

Prerequisites to Set Up Elasticsearch In Magento 2.4

As a required add-on to the Magento platform, Elasticsearch must be installed and configured before users upgrade to version 2.4.x.

Note: Adobe no longer supports Adobe Commerce 2.3.x and PHP 7.3. Upgrade to Adobe Commerce 2.4.x and PHP 7.4.x to preserve PCI compliance.

The installation process for Magento 2.4.x now mandates the installation of Elasticsearch, along with these additional prerequisites:

Note: Magento requires Elasticsearch version 7.6.x for all installations.
