Google added the ability to refine your searches with the “Nearby” tool in the Search Options panel. One of the really helpful things about this tool is that it works geographically — not just with keywords — so you don’t have to worry about adding “Minneapolis” to your query and missing webpages that only say “St. Paul” or “Twin Cities.”
