This is a screenshot of dolphin returning search results for the term "russian"

(the barcode like stuff at the bottom of the picture seems to be a bug in ksnapshot)

The results are completely unrelated in any imaginable why?

Actually for any search term dolphin, strigi, nepomuk or whatever returns completely unrelated results.

What is up there?

KDE 4.6.5 running on Arch.

Thanks!

Probably the word "russian" is present in some ID3 tag in those files, can you check?

Definitely not.

Besides that I checked Filename (=Dateiname), tags shouldn't matter.

I notice that all the files which have been returned contain special characters (those which are not in the normal A-Z set, etc).

It is possible that Nepomuk is somehow mishandling those names. If you remove the Nepomuk database and allow it to reindex completely, does this still occur?

The Nepomuk database can be found at ~/.kde4/share/apps/nepomuk/. It will need to be removed outside of KDE.

Sorry, the usual KDE solution (deleting the database that nepomuk/akonadi/amarok/... corrupted) hasn't worked here, the results haven't changed.

Ok, please file a bug at bugs.kde.org as it seems that Nepomuk has a bug of some description involving those characters. Out of interest, do those files show up for other, non-sensical searches?
