## This next does a number of things:
# 1. It allows you to track all the searches made for stats, etc.
# 2. It fixes the 'searchdesc' variable problem by introducing
# a. 'searchterms' which comes out as 'Keyword: neal stephenson'
# b. 'phraseorterm' which comes out as 'neal stephenson'
# both of these are useful for differen purposes ... I use searchterms
# for display purposes and phraseorterm for passing the search terms
# to an external source through a url (like a database search)
# 3. It provides the variables necessary for the spellchecking (look below for
# how this is done
# 4.
