Google has launched a new search site for US Government information. The search engine limits search results to U.S. federal, state and local sites with domains such as .gov, .mil as well as some selected government sites with .com, .us, and .edu domains.
You can choose to search for content located on either U.S. federal, state and local government websites. If you want you can also use Google's advanced search features with the new site.
