is possible?

it not possible pass requested uri errordocument directive. alternatives are;

1) use php script error handler , grab requested uri php.

.htaccess:

errordocument 404 /404.php 

404.php:

if (!isset($_get['search'])) {          $q = trim($_server['request_uri'], '/');         header('location: http://' . $_server[http_host] . '/404.php?search=' . $q);         die();  } else {          // search code...  }  ?> 

2) use mod_rewrite.

.htaccess:

options +followsymlinks rewriteengine on rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule .* /404.php?search=%{request_uri} [l,r=404]
