   3     MoinMoin - BlurpSearch Macro
   4 
   5     just a modified FullSearch.
   6 
   7     [[BlurpSearch(term, prefix)]]
   8         A category serach, but only for pages beginning with prefix.
   9         If a ##BLURP pragma is on the page, it's contents are displayed
  10         after the match.
  11         The page links are shortened by the given prefix.
  12         The Category is only matched if exactly after a '----' line!
