The new FirstGov search engine powered by Vivisimo and Microsoft has been launched 3 months ahead of schedule. The new search engine for the US Federal Government now indexes over 40 million pages compared to 8 million pages for the previous search site. The FirstGov search engine uses Vivisimo’s clustering technology to cluster similar results for easier searching and uses Microsoft search technology to retrieve results.

You can try out the new FirstGov search engine at FirstGovSearch.
