Limit your Google search to a specific domain, such as .mil, .gov or .edu, to ensure you are accessing quality information from trusted sources.
Simply add: site:. and the domain to the end of your search in the Google search box. For example: robots site:.mil will return only information about robots from U.S. military websites.
You can also use this type of search on a specific website; adding site:.navy.mil will return information specifically from Navy military websites.
