12. A computer-implemented method comprising: identifying a collection of terms, wherein the terms in the collection are terms identified from search queries; determining, using one or more processors, a degree of implicit local relevance for each term in the collection with respect to each of one or more geographic locales, including evaluating each term in the collection with respect to one or more local relevance criteria and where the terms do not explicitly identify a locale; and storing the collection and the determined degrees of implicit local relevance in a repository; wherein a degree of implicit local relevance for a respective term with respect to a locale indicates a correlation of search queries that include the respective term with search results that are directed to the locale.
