Abstract
A system and method for performing geographic based document searching. A grid of location tiles is constructed corresponding to a desired geographic area. A location tag is assigned to each location tile. Documents are searched to identify a geographic location. The documents are associated with one or more location tags based on the location tiles corresponding to the identified geographic location. The geographic location of a search query is also identified. The search query is modified to include one or more location tags corresponding to the location of the search query. The search query is then matched to documents associated with location tags contained in the search query.
