[opensuse-kde] Broken Nepomuk support in KRunner and Lancelot?

I just followed a discussion at forum.kde.org about broken Nepomuk support in Lancelot and KRunner which I can relate to. I use KDE 4.10.3 and only Dolphin perfectly supports Nepomuk search. When I type in the fraction of a filename, Dolphin finds it. KRunner and Lancelot does not find it. Lancelot and KRunner only find a file when I type in the full name, but this is not how search is meant to work. Neither Lancelot, nor KRunner find a file when I type in only the fraction of the file name. Dolphin does. Can someone confirm this? File a bug report? Malte
