Prestashop Elastic Search

ElasticSearch is a type of search engine that provides fast search responses.

This speed is achieved because ElasticSearch searches an index instead of the text directly, similar to how we retrieve pages in a book by using its index.

Elastic search is actually a highly scalable open-source full-text search and analytics engine.  It allows you to store, search, and quickly analyze the big volumes of data in near real time.
