Google Maps has localized search and how. With Google's new Neighborhood Search feature users can search for items with the use of colloquial/ local slangs and popular terms.
At the Google Lat Long Blog, David Tussey, the Product Manager of this application writes, "Neighborhoods tend to be somewhat informally defined but well recognized in certain cities. Neighborhood search is now available in fifty US cities, with more to follow."
However, Google Maps is not the first to offer localized service such as this. Real Estate portals, HomeGain and Trulia also boast of this this feature. Yelp and Ask City also have comprehensive details on local database.
