Elasticsearch REST API

Distributed search and analytics engine for real-time data

Elasticsearch is a distributed, RESTful search and analytics engine built on Apache Lucene. It enables full-text search, log analytics, application monitoring, and real-time data analysis at scale. Developers use Elasticsearch to power search functionality, analyze massive datasets, and build observability solutions with lightning-fast query performance.
