I've used the Fedora RPMs and they work fine, but at one point in the past -- I don't exactly remember when -- the "type" filter in aMuleweb seemed to interfere. Try a search without specifying the file type in the drop-down menu.
Be sure to wait a few seconds before clicking "Refetch Results". If you do a search for a common file name on your local server, it should return dozens if not hundreds of hits.
