Abstract
Systems, methods, and computer-readable storage media are provided for establishing a search radius based on token frequency. A search query having a geographic indication is received and it is determined whether or not the received query contains one or more non-frequent tokens. Non-frequent tokens have a respective frequency that occurs in the entities included in a data store of entities below a threshold number of times. If it is determined that the received query does not contain one or more non-frequent tokens, the search radius established for the search query, and thus applied to the search, is restricted to a radius established based upon the geographic indication of the query. If it is determined that the received query does contain one or more non-frequent tokens, the search radius is established such that it is larger than if it was established based upon the geographic indication of the query.
