20. A computer-implemented method comprising: receiving, at a computer server system from a remote device, a search query; determining a geographic location to associate with the search query; generating a first set of search results using the received search query and the determined geographic location; generating a second set of search results using the received search query but not the determined geographic location; determining for the received search query a local relevance indicium that indicates whether a user who submitted the search query is likely to be more interested in the first set of search results or the second set of search results; formatting a message having content, for transmission to the remote device, so that when the message is initially displayed on the remote device one of the first set of search results or the second set of search results is initially displayed in preference to the other set of search results based on the local relevance indicium that indicates whether the user is likely to be interested in the first set of search results or the second set of search result; and transmitting the message to the remote device; wherein the local relevance indicium is generated by a machine learning system that has been trained on prior search queries.

The method of claim 20 , wherein the local relevance indicium is generated from a list of search queries predetermined to be particular relevant to local results or particularly non-relevant to local results.
