 Power Searching The little text box above conceals a myriad of useful tools for a power user, 
  which you doubtless are. The search will, by default, return a list of results 
  which include any of the given query words (however, results which include 
  more of those words will be ranked higher) If you require that all results returned 
  must include a given word, precede that word with a + sign. If you require 
  that all results must not include a given word (for the purpose of whittling 
  down results), precede that word with a ! sign. Note that there should 
  be no spaces between signs and the words they apply to. For example, the query  +hitch !book infocom  will return only results that contain the word "hitch" and do not 
  contain the word "book". Results containing the word "infocom" 
  will be ranked higher. |    |  | |||
