Abstract
A travel coordination system identifies geographic locations responsive to a location search request. The geographic locations are organized into a plurality of hierarchical geohash levels, each geohash level mapping the geographic location into a geohash of a different area. The locations search request designates a search context for the search, such as whether the user is searching for an origin of a trip or a destination. The context of the search can be used to determine a geohash level for selecting candidate search results. The candidate search results may be scored based on the context using prior user selections and trips scheduled with the trip coordination system. A geohash and context associated with the user's request may be used to modify a scoring function of the candidate search results based on prior trips.
