If you’d like to limit your searches to a specific domain, such as .edu, .org, .gov, and more, you can use the site: command to accomplish this. This works in most popular search engines and is a great way to narrow your searches to a very particular level. For example, say you only wanted to search U.S. government-related sites for something. You could limit your search results to only government sites simply by typing site:.gov “my query”. This will bring back results only from sites that are in the .gov high-level domain.
