An approach is provided for automatic geo-location and social group indexing thereby search geo-locations. A geo-location search learning platform receives a query specifying words, and retrieves context information of a user based upon a criterion. The geo-location search learning platform then assigns to the user a social group identifier identifying a social group based on the context information, retrieves one or more social group indexes based upon the social group identifier, retrieves one or more geo-location indexes based upon the one or more social group indexes, and generates a search result using, in response to the query, the one or more geo-location indexes and the words.
