Ranked by capability fit
Postgres full-text search vs OpenSearch — the tradeoffs that decide it
- Operational burden: Postgres full-text search — Low operational burden (managed or lightweight). OpenSearch — Cluster/shard/JVM ops are real work — heavy for a minimal-ops team.
- Typo tolerance: Postgres full-text search — Weak/absent typo tolerance — relevance suffers on misspellings. OpenSearch — Built-in typo tolerance / fuzzy matching (documented).

This is a capability-fit decision, not a price ranking — these tools bill in incompatible units (per-search vs per-RAM cluster vs per-PB scanned) and several publish rates only in their own calculators, so StackSays does not invent a unified dollar comparison. Every score above traces to a documented capability; see Data sources below.
