Keeping your knowledge base answer-ready (semantic search)

Keeping your knowledge base answer-ready

The Auto-Responder and the Widget Answer agent are only as good as the articles they draw from. Helmdesk uses semantic search — matching on meaning, not just keywords — so a visitor who asks "how do I log in with Google?" finds your "Single sign-on" article even if it never uses the word "login."

How retrieval works

  • When you publish or edit an article, Helmdesk computes a vector embedding of its content.
  • A question is embedded the same way and compared against your articles by semantic similarity.
  • The most relevant published articles are passed to the agent, which grounds its answer in them and cites them.
  • If semantic search is unavailable, Helmdesk falls back to keyword search, so retrieval still works.
  • Only published articles are searchable — drafts (including agent-drafted articles awaiting review) are never surfaced to customers.

    Writing articles agents can use

  • Answer one question per article, and make the title that question.
  • Be self-contained — the agent answers from a single article, so don't rely on the reader having read another.
  • Use clear headings and short paragraphs so the most relevant passage is easy to retrieve.
  • Keep them current — re-editing an article refreshes its embedding automatically.
  • The payoff compounds: every good article improves your public knowledge base, your widget answers, and your Auto-Responder drafts at the same time.
