Turn 404 url into search

I want to transform all 404 urls into search strings. This is easily done by adding this to 404.php:

$search_term = substr($_SERVER['REQUEST_URI'],1);
$search_404 = str_replace('/','+',$search_term);
$search_404 = str_replace('-','+',$search_404);
$location = "http://example.com/?s=" . $search_404;
session_start();
$_SESSION['search_404'] = true;
header("location: $location");

There should also be some sanitization, but that's not the point right now.

What I want further is to do without the "?s=", so the url stays unchanged but have the search still work. Is this possible/how?

(I don't worry too much about SEO, as the pages are noindexed anyway, but I do worry about potential conflicts with existing pages or security holes)

Update: Apparently, this should be simple if wp itself would use search as last resort when everything else fails, i.e. if there's no post, page, category, tag etc. with a given url, start the search query... is there a way to alter the template hierarchy so as to put search last?

OK, it looks like one way around this is to ignore the search template and use the very 404 template instead - like this:

$search_term = substr($_SERVER['REQUEST_URI'],1);
$search_404 = str_replace('/','+',$search_term);
$search_404 = str_replace('-','+',$search_404);
$args=array('s'      => $search_404, );
query_posts($args);
if(have_posts()) { while (have_posts()) : the_post(); 
// WHATEVER
endwhile; wp_reset_query(); }

The thing does the job now.

Am still curious if there may be any conflicts or security holes and if the page still returns a 404 or not.
