  96 ## This next does a number of things:
  97 # 1. It allows you to track all the searches made for stats, etc.
  98 # 2. It fixes the 'searchdesc' variable problem by introducing
  99 #         a. 'searchterms' which comes out as 'Keyword: neal stephenson'
 100 #         b. 'phraseorterm' which comes out as 'neal stephenson'
 101 #      both of these are useful for differen purposes ... I use searchterms
 102 #      for display purposes and phraseorterm for passing the search terms
 103 #      to an external source through a url (like a database search)
