Getting started with Elasticsearch, elasticsearch Elasticsearch is a highly scalable open-source full-text search and analysis engine. It can store, search, and analyze large-scale data quickly and in near real time. It is generally used as the underlying engine/technology to provide powerful support for applications with complex search functions and requirements
