发明名称 POLYGON-BASED INDEXING OF PLACES
摘要 In one embodiment, a method includes receiving an identification of a location. The method further includes accessing an inverted index that comprises a plurality of records, where each record corresponds to a map tile and identifies one or more places corresponding to the map tile. At least one of the places identified in the inverted index is identified in multiple records corresponding to multiple map tiles, where the map tiles collectively define an area that circumscribes the place. The method also includes identifying based on the inverted index one or more places associated with the location.
