Putting Some Refinement Into Your Open Internet Searches

The Virtual Chase has a useful page on using advanced commands on the Web.  One tip is to add (site:.gov) to your searches to limit your results to .gov websites.  And did you know that Google lets you search synonyms by putting a tilde (~) in front of the pertinent search term?  For example, searching second amendment ~guns brings up results including the words firearms and arms as well as guns.
