Sometimes your docs do not cover a question, or cover it ambiguously, and the agent’s answer suffers. The fastest fix is usually a Q&A pair.
A Q&A pair is what it sounds like: a question and the answer you want given. It sits alongside your other sources and is matched the same way, but it lets you correct a specific gap in seconds without rewriting a whole article.
Use them for the long tail
Q&A pairs shine for edge cases: the unusual refund scenario, the regional shipping quirk, the “can I do X” question your docs never quite addressed. Add a pair, and the next customer who asks gets the right answer straight away.
