A system receives a search query that includes a set of search terms,
determines whether at least one of the search terms corresponds to the
name of a geographic area, and determines whether the geographic area
corresponds to an unambiguous geographic area when at least one of the
search terms corresponds to the name of the geographic area. The system
performs a local search, based on one or more of the search terms, to
identify documents associated with the geographic area when the
geographic area corresponds to an unambiguous geographic area.
