Abstract: Aspects of the invention relate generally to providing useful search results from chain business queries. More specifically, various algorithms may be used to identify chain businesses and queries for chain businesses. Chain businesses may include, for example, various types of businesses which are associated with other businesses with the same name, such as chain restaurants, car rental locations, pharmacies, banks, retail stores, or other franchise businesses. This information may be used to rank and filter search results as well as incorporate other useful features in order to improve a user's search experience.
