Found a problem searching Drupal sites that use 'clean urls'. It even happens on the main Drupal site. Just do a search for 'die/die' and you get the following error:
Not Found The requested URL /search/node/die/die was not found on this server. Apache/1.3.33 Server at drupal.org Port 80
Clean urls requires a mod_rewrite hack to turn
http://www.drupal.org/search/node/die/die
into
http://www.drupal.org/index.php?q=search/node/die/die
but this is not working properly. If you try the second form above in a browser then it works, the search is done but mod_rewrite does not seem to correctly munge it.
