You’ve probably heard about Elasticsearch if you use Magento 2. So what is it specifically, and how does it function in Magento 2? We’ll get into Elasticsearch’s specifics and how Magento 2 employs it in this article.

Elasticsearch in Magento 2: An Overview

An open-source, distributed search and analytics engine is Elasticsearch. It is made to manage enormous amounts of data and enable real-time searching. Elasticsearch is utilised for catalogue search in Magento 2. This implies that Elasticsearch is in charge of locating and returning the pertinent results when a user searches for a product on a Magento 2 website.

So why choose Elasticsearch instead of the established MySQL search? Elasticsearch’s speed is one of its primary advantages. Elasticsearch is made to handle big amounts of data and is much faster than MySQL at returning search results. Its capability to handle challenging search queries is an additional advantage. Partially matched results can be found using Elasticsearch, among other things. Users can now find what they’re looking for even if they don’t know the specific search term, thanks to this.

Another essential component of the search engine is elasticsearch indexing. All of your catalogue data is initially indexed by Elasticsearch when it is installed in Magento 2. This indicates that Elasticsearch will review your product data and build an index of all the information. Elasticsearch retrieves search results from this index. Elasticsearch will automatically update the index each time you make a modification to your product data.

Magento 2 Elasticsearch Configuration

The method of setting up Elasticsearch in Magento 2 is simple. Make sure your server satisfies the prerequisites for running Elasticsearch first. This entails having a 64-bit operating system and at least 4GB of Memory. Moreover, Java 8 or a later version must be installed on your server.

Once the prerequisites have been completed, you can install Elasticsearch using a package manager or the command line. Elasticsearch must be configured in Magento after installation. To do this, configure the Elasticsearch connection in the Magento 2 admin panel. You must configure the indexing options and enter the information for your Elasticsearch server.

Elasticsearch usage in Magento 2

You can begin utilising Elasticsearch for catalogue search once you’ve configured it in Magento . Elasticsearch will automatically deliver the pertinent results when a user searches for a product on your website. Elasticsearch can be used to resolve any search-related problems you may be having. For instance, you can utilise Elasticsearch to monitor how the search query is being processed and troubleshoot any difficulties if you’re not getting the intended search results.

There are a few things you can do to enhance Magento 2’s Elasticsearch performance. Increase the quantity of Elasticsearch shards first. Elasticsearch distributes data around the cluster via shards. Elasticsearch employs 5 shards by default, however you can raise this amount to speed up search results. Your product data can also be prepared for Elasticsearch. This entails ensuring that your product data is accurate, consistent, and that the appropriate data types are being used in each area.

Conclusion

Elasticsearch is a potent search engine that may significantly enhance the functionality and performance of your Magento 2 website. Your users will receive quick and precise search results if you use Elasticsearch for catalogue search. It’s simple to set up Elasticsearch in Magento , and there are a tonne of resources you can use to solve any problems you may run across. You can fully utilise this potent search engine by optimising Elasticsearch performance and making sure that your product data is accurate and consistent.
