  "summary": "The article discusses the importance of a staged retrieval design for travel itinerary planning, advocating for a cache that stores stable itinerary facts while re-checking any changeable elements during a trip. The author argues that caching should be an integral part of the retrieval contract, rather than a separate speed optimization. The decision between using a managed retrieval surface or a search stack depends on factors such as freshness, filter complexity, and operational work. The article recommends mapping the user-visible answer to retrieval units, using explicit collections with bounded queries, and keeping a traceable source context for each piece of information. The author also emphasizes the need to differentiate cache policies for stable and changeable itinerary facts, and to include metadata like retrieval timestamps and source URLs for auditing and freshness control. The proposed caching strategy involves separating document caches keyed by source URLs and query-result caches keyed by normalized intent, destination, date range, traveler constraints, and collection. The article concludes with a comparison of a simple cache versus a staged retrieval system, highlighting the importance of semantic accuracy over mere cache hit rates.",
