The National Park Service and the Google Search Appliance
A bureau of the U.S. Department of the Interior, The National Park Service (NPS) has protected America's parks and monuments since 1916. Federal government's proprietary search tool, FirstGov, was not delivering complete or accurate results, which meant the NPS was hearing from frustrated users. NPS deployed Google Search Appliance which has to learn from what people are searching for in order to develop new content areas. Also, it was implemented Google search on its intranet site as well.
