The Polisphere customized search engine searches and indexes information from more than 3,300 websites of elected officials, think tanks, research and advocacy organizations, and other public policy websites. Built using Google's Custom Search Engine technology, this tool will help you find the most relevant political and public policy information by filtering the unnecessary results produced by ordinary search engines. The Polisphere search engine also allows you to further tailor your searches by clicking one of the customized "refinements" to receive results from only those types of websites.
