Search Meeting Minutes

Search meeting minute chunks via Postgres FTS.

At least one of institution_ids or query must be supplied — chunks table has 20M+ rows and we don't allow unbounded scans.

With query: results ranked by ts_rank_cd (cover density — proximity of query terms). Without query (institution-scoped browse): results sorted by meeting date descending.

query accepts a websearch-style string (same syntax as RFP / Grant search): bare words for stemmed match, "phrase" for exact phrase, OR, -word for exclude.

Set group_by_document=true to collapse to the highest-scoring chunk per document (or earliest chunk when no query).

Semantic / LLM-synthesized answers are not in scope here — use the existing /v3/rag/query endpoint for that. This endpoint returns raw evidence rows for downstream reasoning.
