16. The system of claim 15 , wherein the operations further comprise determining that the search query is received from the searcher via a mobile device, wherein generating the location model comprises generating a first location model for queries received from mobile devices and generating a second location model for queries received from fixed-location devices, and wherein identifying the unambiguous location for the search query using the location model comprises identifying the unambiguous location for the search query using the first location model based on the search query being received from the searcher via the mobile device.
15. A system, comprising: a processor; and a memory that stores instructions that, when executed by the processor, cause the processor to perform operations comprising receiving a search query having location ambiguity, generating a location model using a machine learning technique, the location model generated, at least in part, based on a personalization feature, wherein the personalization feature comprises a location corresponding to a past result selected by a searcher, wherein generating the location model based, at least in part, on the personalization feature comprises generating a training dataset comprising the personalization feature, wherein generating the training dataset comprises filtering a query log to identify a first query, the first query specifying an unambiguous location, generating, from the first query, a second query having location ambiguity by removing a first component of the first query, wherein removing the first component comprises breaking the first query into the first component and a second component, and removing the first component, identifying a location candidate for the second query, and generating a training target based on comparing the unambiguous location specified in the first query and the location candidate for the second query, identifying, using the location model, an unambiguous location for the search query to resolve the location ambiguity, and determining a search result corresponding to the search query directed to the unambiguous location for the search query.
