Semantic Search

Search that finds results based on what you mean, not just which words you typed. Traditional keyword search requires your query to match the exact words in the document. Semantic search uses AI to understand that 'how to remove someone from my account' and 'delete a user' mean the same thing — and surfaces relevant results either way. It's how AI-powered support search feels smarter than old-style site search.

In practice

An employee searches your internal HR system for "parental leave." A keyword search only finds documents containing those exact words. A semantic search also finds documents about "maternity policy," "family leave," and "new baby benefits" — because it understands meaning, not just words. Semantic search is what powers smart knowledge base tools.
