Supabase Knowledge Search
Z-Shell Knowledge Search indexes public wiki documentation into Supabase so maintainers can run source-linked semantic search across the docs.
GitHub repositories and the wiki remain the source of truth. Supabase stores derived metadata, chunks, and embeddings only.
Secretsโ
SUPABASE_URL: Supabase project API URL.SUPABASE_DB_URL: direct Postgres connection string for server-side ingestion.SUPABASE_SECRET_KEY: server-onlysb_secret_*API key for maintainer CLI calls.SB_SECRET_KEY: the samesb_secret_*value exposed to theknowledge-searchEdge Function.OPENAI_API_KEY: embedding provider key.
Do not expose server-side secrets in browser code.
Indexโ
pnpm knowledge-search:index
The indexer scans docs/, community/, and ecosystem/ Markdown and MDX files, chunks the content, generates embeddings, and upserts rows into the private docs_search schema.
Queryโ
pnpm knowledge-search:query "release policy"
The query command calls the knowledge-search Edge Function with SUPABASE_SECRET_KEY in the apikey header and prints source-linked results.
Access Controlโ
The docs_search schema is private. Public search uses the public.match_public_docs function, which returns only sources marked public.
The knowledge-search Edge Function has verify_jwt = false because Supabase secret keys are API keys, not JWTs. The function checks the apikey header itself before running a query.
