FirstGov, the federal government’s official web portal, has undergone a face lift.  It now features a revamped search engine that uses Vivisimo’s clustering technology to group search results by subject -- you can click here for an example of a clustered search result from FirstGov. According to news sources, the old FirstGov search engine only searched approximately 8 million government publications.  Currently, the search engine accesses 40 million government documents, some of which are not available on other commercial search engines.  Be sure to explore the extensive topic-specific links to government resources on FirstGov’s home page as well!
