Why this fits

  • Catalogs and docs where keyword search clearly fails

Watch-outs

  • Cases that need conversational answers (use RAG instead)

Key features

  • Meaning-based ranking with embeddings
  • Hybrid keyword + vector retrieval
  • Re-ranker for the top results
  • Click-through and zero-result analytics
  • Per-source access filtering

Key benefits

  • Help users find what they actually meant

Risk, liability & governance

General guidance for this category — confirm specifics with your legal, security, and compliance teams.

Risks

  • Stale or out-of-date answers when indexes lag
  • Over-broad permissions surfacing restricted content
  • Confident answers without citations

Liabilities

  • Unauthorized disclosure of confidential or regulated information
  • Decisions made on outdated policy or guidance
  • Breach of confidentiality obligations with customers or partners

Governance controls

  • Enforce source ACLs at query time, not just at ingestion
  • Require citations and show source freshness
  • Document index scope, refresh cadence, and excluded sources
  • Access reviews and query auditing

Pilot plan — next steps
