Knowledge

Retrieval over Miles' points-and-miles knowledge base, for explanation and strategy questions the structured tools don't cover.

knowledge_search

Retrieval over indexed points-and-miles articles, guides and reviews -- reach for this when a question needs explanation or strategy that Miles' structured tools don't cover: how a transfer bonus mechanic actually works, what changed about a lounge network, how to think through a redemption trade-off. If the answer is a fact about the member's own wallet or the card dataset -- current benefits, transfer ratios, eligibility -- use the structured tool for it instead (get_card_info, get_transfer_partners, get_wallet_summary); those cost nothing beyond the shared per-day ceiling and are exact, and this tool is not a substitute for them.

Scope	Quota
`miles:read`	expensive

Name	Type	Required	Description
`query`	`string`	required	A short topical phrase naming the subject and any specific program, card, or place involved, e.g. `Chase trifecta card combination` or `Hyatt points expiration policy`. Not the member's question restated verbatim, and not a bare keyword list: search runs a semantic match and exact-term matching, so naming the specific entity matters most.
