How Magento 2 Elasticsearch Is Better Than Others? What is Magento 2 Elasticsearch? Elasticsearch was introduced as a full-text search solution that not only suggests related keywords, but also shows complete queries based on queries. However, elasticsearch is not limited to search queries alone. It can also be used to install store-wide search capabilities. Magento 2 Elasticsearch is a server-based tool capable of full-text search at a very fast speed. Powered by Apache Lucene (an open-source full-text search library), it provides a fast web content search capability. The reason behind the rapid response is the index service used for contextual search rather than searching the entire database to match.
