I wasn't quite sure which forum was best to put for questions about nepomuk and underlying technologies so I apologize in advance if I'm completely out of context

Ever since I've upgraded to 4.4 (beta1, now beta2), I notice that typing in words in krunner does not return results from my indexed files. In system settings both "Enable Nepomuk Semantik Desktop" and "Enable Strigi Desktop File Indexer" has been checked, the Nepomuk/Strigi icon is in my systray and every so often indexes my files, hovering over it shows it to be progressing through directories, searching using the search bar in Dolphin returns results successfully, and the plugin "Nepomuk Deskop Search Runner" is enabled in KRunner plugins. I am using Virtuoso and I've never noticed any errors of any kind, and when running krunner from a console it loads all 22 runners succesfully without complaint.

Despite this krunner still does not return any nepomuk results.

At the same time a few other runners don't seem to do anything either (such as the media player control with amarok, or the contacts or kopete runner) and I notice sometimes it freezes (alt-f2 doesn't bring up krunner immediately or it remains inactive after typing in something into krunner). I do notice that (launching krunner from a terminal) after typing I get this: "krunner(11327)/plasma Nepomuk::SearchRunner::match: Plasma::RunnerContext(0x2b74b98) "hello"", where hello is what I've typed.

Any ideas?

Seems like kio_nepomuk is broken in KDE 4.4 and problem is not solved yet. It's a little bit frustrating because without queries Nepomuk is useless.

https://bugs.kde.org/show_bug.cgi?id=217841

On the other side, Dolphin is frozen again time to time with Nepomuk enabled .

Please file a bug report regarding the broken KIO slave.

This accounts for the no results, but is this likely to cause the freezing and the contacts/kopete/amarok runners not working either? (unsure if nepomuk also handles those things)

The nepomuksearch kio slave is not used by krunner. But the Nepomuk Queryclient lib.

The problem is it works here. (Though using kde 4.4 sc trunk) Are you sure you have a file with that name?

You can try to do it with fresh Nepomuk repository. (Delete/Backup the folder in .kde/.kde4/share/apps/nepomuk/repository when Nepomuks is disabled) And then let it index some directory (best to configure only a small one with a few files to test). And try then.

A user for testing where I disable nepomuk, delete the db and enable nepomuk again.

I have three files: "01 uno.txt", "02 dos.txt" and "03 tres.txt" and I assign different tags to anyone.

Both, krunner and nepomuksearch:/, don't works.

I'm using openSUSE 11.1 KDE 4.4 Beta 2 and, when I write this entry, I'm updated. I have this problem since I updated to KDE 4.4 Beta 1 but I can see all my tags using Dolphin or Pimo. If I use sopranocmd I can execute a SPARQL query and works fine so, as far I can see, db was correct.

I could see that, time to time, virtuoso stops working when Dolphin crash and I must quit nepomukserver, send a TERM signal to virtuoso, and run nepomukserver again. If I don't do the previous steps neither Dolphin or Pimo don't show any nepomuk data.

I would like to stress that everything works fine from the dolphin search, it only doesn't work in Krunner.

I have deleted my .kde directory and it didn't help.
DanielW, you say you are running trunk, do you recall this problem happening before? Say, in the time of Beta1? If so it could be that it was recently fixed.

I'm testing RC 1 and KRunner nepomuk search is working again but sadly nepomuksearch:/ is still broken .

I hope that this will be fixed in RC 2.

Both work for me now (RC1)

Both doesn't work for me...using virtuoso backend and RC1. If i try nepomuksearch:/ or the searchbar in the dolphin - it just gives no results found. even if I see from tray it's indexed already

There is always the possibility that you are using redland/librdf 1.0.9 which seems very broken. In that case please try updating to 1.0.10 or downgrading to 1.0.8.

KDE SC 4.4_RC2, fresh nepomuk index, gives no result. I use virtuoso backend because I read that redland is slow. Does it work with redland backend?

redland is used for temporary memory models, not for data storage. Anyway, I fixed a big today which could be the reason for your problem, too: http://bugs.kde.org/show_bug.cgi?id=220072
