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