OpenSearch
OpenSearch is a distributed search and analytics engine. Use it when you need
full-text search, faceting, or aggregations over large document sets — the
things a relational LIKE query does slowly and badly.
When to use it
Section titled “When to use it”- Full-text search across products, documents, or logs.
- Faceted / filtered search with relevance ranking.
- Log and event analytics with aggregations.
Connecting
Section titled “Connecting”When your instance is ready, copy the connection string from its detail page
and use it with any OpenSearch (or compatible Elasticsearch) client.
OpenSearch is a search index, not a system of record. Keep the source of truth in Postgres and index into OpenSearch for the query patterns it’s built for.
