OpenSearch

AI-Assisted Forked Code Search Engine

OpenSearch is an open-source search and analytics suite that provides full-text search, log analytics, application performance monitoring, and observability capabilities. It is built on Apache Lucene and supports distributed deployments for scalable data indexing and querying.

History

The project was initiated in April 2021 by Amazon Web Services as a fork of Elasticsearch following Elastic NV's license change to the Server Side Public License (SSPL) and Elastic License v2.

Amazon then donated the source to the Linux Foundation under the OpenSearch Software Foundation, transitioning to a community-governed open-source project.
