I can't explain the behaviour but here it is. Try to find the following (existing) files on mediawiki.org using the standard search. Testnameforsearch foo.png Anothertestname.png Funkadelia test name.png Iuftrekdjhlsfbhs.png linked here: http://www.mediawiki.org/wiki/User:Subfader/2/3/4 They are not found. Not even Iuftrekdjhlsfbhs.png which doesn't include stop words. The tricky thing is, you will only find this bug when you know the files you search for does exist and you wonder why it doesn't show up in the result. As a wider test, Iuftrekdjhlsfbhs.png couldn't be found after upload on my wiki, on mediawiki.org and commons.wikimedia.org
Hmh, works fine now. But still on my wiki it doesn't work. http://www.mixesdb.com/db/index.php?title=Special:Search&search=Iuftrekdjhlsfbhs&fulltext=Search&ns6=1&redirs=0 doesn't find http://www.mixesdb.com/db/index.php/File:Iuftrekdjhlsfbhs.png
Which search engine does your wiki use? Note that on Wikimeadia it could take some time before things are indexed.
Guess so about the indexing. I don't use Lucene. No search engine installed.
