rewrite vs. 404

[saraadmin]

I'm just trying to provide some backwards compatibility to on old version of my PHP database.

I've got the following RewriteRule:

RewriteRule ^/search_from_listings\.php\?artist_id=([0-9]+)$ /?artist&id=$1 [R]

which I want to direct requests like:

http://www.sara.uea.ac.uk/search_from_listings.php?artist_id=96

to

http://www.sara.uea.ac.uk/?artist&id=96

However, I just get a 404. cannot find 'search_from_listings.php'.

Does anyone know why its returning 404 in preference to following the RewriteRule?

Cheers,

(Apache 2.0.54)

OK, this is getting really desperate.

Why does this match:
RewriteRule ^/search_from_listings.php?(.*)$

http://localhost/$1

while this doesn't:
RewriteRule ^/search_from_listings.php?artist_id=([0-9]*)$

http://localhost/?artist&id=$1

If anyone has absolutely any ideas at all please just tell me!

OK, I've managed to work this out now:

RewriteCond %{QUERY_STRING} ^artist_id=([0-9]+)$
RewriteRule ^/search_from_listings\.php$

http://localhost/?artist&id=%1
