# Elasticsearch

Elasticsearch is a NoSQL, document-oriented database management system having a full-text search engine at its heart. Built on the Apache Lucene library, it stores data as a JSON file, supports RESTful APIs, and uses a powerful analytical engine for faster data retrieval. Being open-source software, it includes both free and paid editions.
