// NAME: 404 search
// VERSION: n/a
// AUTHOR: Erik J. Barzeski
// WEBSITE: http://nslog.com/
// DESCRIPTION: A function to replace the 404 with a search page 
// particularly for blogs with the search term included e.g. 
// http://nslog.com/blah .  Wrap this up in a 404.php file and set 
// your .htaccess file to read "ErrorDocument 404 /404.php" or 
// something.

  *the REQUEST_URI is the string after the .com so if I have 
  *www.vinayvenkatesh.com/blog/search
  *then this would be "/blog/search" so by saying 6, 
  *I cut out the first 6 characters of that string "/blog/" and set
  *the term I'm searching for to "search".
