How to Configure Magento 2 Elasticsearch

Search functionality is undoubtedly one of the most crucial features of any online store.

A powerful search helps the visitors find their desired products on the Magento 2 store quickly. It contributes to the improved in-store experience and quick purchase decisions.

Whereas, if customers don’t get instant search results, they tend to bounce back and move on to your competitors.

Therefore, it’s essential to enhance the search feature, and Elasticsearch is one of the best ways to improve the search feature in Magento 2 stores.

The store admin can configure Magento 2 Elasticsearch to use its features like an open-source, readily-scalable, analytics, broadly-distributable, enterprise-grade search engine including textual, numerical, geospatial, structured, and unstructured.

One thing that is noteworthy to mention here is that Elastic search is not compatible with varchar fields. Therefore, it is essential to disable the varchar fields for the elastic search. Many of the store owners reported an Elastic Search Error: ‘Text Fields are Not Optimised for Operations’ in Magento 2.4.x, which was caused by the varchar fields ser filterable in elastic search.
