/* Modified 20021006 to fix query string parsing and add case insensitivity */
/* Modified  by webdesign.weisshart.de:
   20050530: added for site search - where target-file is called with ?q=searchword 
             unescape -> decodeURI, to cope with german Umlauts
   20050611: remove all blanks and '+' before and after searchterm (bugfix: crashes FF & Op) */
