Google’s “” function, which lets you search for a term inside a specific web site. Now the search engine has made it possible to do this-site-only searches from a search box underneath certain top results (based on, the company says, “metrics that measure how useful the search box is to users”). It might be convenient if you stumble upon a site you didn’t know about in your own searching, but it’s also an easy way to help your less web-savvy Uncle Bif and Aunt Marge find what they’re looking for, rather than explaining the semantics of search to them.
