About OpenSearch
OpenSearch is a community-driven search and analytics suite licensed under Apache 2.0. It covers full-text search, log analytics, dashboards and vector search.
What it does
OpenSearch indexes documents so you can search them quickly, with relevance tuning and filters. Alongside the search engine, the project offers OpenSearch Dashboards for charts and data exploration, Data Prepper for filtering and enriching data on the way in, and tools for migration and benchmarking. The engine is built on Apache Lucene, and it includes vector search for semantic queries and anomaly detection for spotting unusual patterns in data.
