Many people do not realize that their browser address bar can act as a search engine. For example, instead of a URL, you can enter a search query, such as “Who is Barbara Feldman?” Here are instructions from Google on how to change your default search engine. Of course, these instructions assume you are changing your default to Google (http://www.google.com ) . To change to MSN Search (http://search.msn.com ) or Yahoo! ( http://www.yahoo.com ) just use their URL instead.
