Full-Text Search with Managed OpenSearch: From Zero to Production
Every application eventually outgrows LIKE '%query%'. Once your product catalog, help center, or log pipeline crosses a few million documents, you need an inverted index, not a sequential scan. OpenSearch provides exactly that: full-text search with relevance scoring, custom analyzers, aggregations, and a visualization layer built in.
The hard part is running it. JVM heap tuning, cluster formation, TLS certificate management, shard rebalancing, and snapshot configuration turn a "quick search feature" into a permanent ops project. FoundryDB removes all of that. You get a managed OpenSearch 2.19 cluster with TLS, authentication, automated snapshots, and monitoring out of the box.
This guide walks through deploying OpenSearch on FoundryDB and building production-quality search: from provisioning to index design, full-text queries, custom analyzers, and aggregations.
