Abstract: A method of generating search suggestions includes receiving an indication of a current location of the user device. After a user accesses a search function on the user device and before the user submits a search request, the method includes determining search results associated with locations in proximity to the current location of the user device, using query log data indicating selections of past search results by users after presentation of the past search results in response to respective past queries. The method also includes determining relative positioning of the search results based on the number of users that selected each search result, determining categories associated with the search results, grouping the search results by the determined categories; and sending the grouped search results and the one or more categories associated with the search results to the user device for display according to the determined relative positioning.

Abstract: Methods, systems, and apparatus, including computer programs encoded on one or more computer storage devices, for predictive generation of search suggestions. The methods include receiving a first location from a user device. The methods include determining, prior to receiving a search request, search results associated with locations in proximity to the first location. The methods also include sending the search results to the user device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for annotating search results. In one aspect, a method includes receiving a notification request, the notification request for identifying when to send a notification from the server system to a device, the notification request includes a device identifier, message text, and a location identifier. The method also includes receiving information corresponding to a current location of the device and information corresponding to an identity of the device. The method also includes determining that the information corresponding to the current location corresponds to the location identifier of the device from the notification request and that the information corresponding to the identity of the device corresponds to the device identifier from the notification request. The method also includes sending the notification, including the message text, to the device.
