      summary: Search Meeting Minutes
      description: '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.'

      description: 'Search filters for meeting minute chunks.


        The ``query`` field accepts a websearch-style query string evaluated against

        the chunks'' ``text_search_fts`` column (english config — stemming enabled).

        Same syntax as RFP / Grant search.


        Semantic search lives on the existing ``/v3/rag/query`` endpoint (returns

        synthesized prose). This endpoint returns raw matching chunks for callers

        who want to reason over evidence directly.


        At least one of ``institution_ids`` or ``query`` must be supplied — the

        chunks table is 20M+ rows and we reject fully unbounded scans. Institution

        scoping alone (with no query) lists that institution''s chunks in

        reverse-chronological order, useful for surveying what we have.'
