Is Nepomuk (search in Dolphin) completely useless?

Is Nepomuk (search in Dolphin) completely useless?
Using 10.04 the Dolphin search tool seems completely useless--it can't find anything--it indexes, then returns no results.
It is turned on. Is there any point in messing with this, or should everyone just install Krusader?

Any suggestions?

Here the Nepomuk & Strigi are working fine. If the "keyword" is in the Nepomuk database then the Dolphin and/or KRunner is showing the hits.

Searching with the artist/composer.

The Nepomuk is a new and developing application. There are lot of alternative applications:

Not sure why it isn't working for you,
There is still the option to use Kfind, go to Tools - Find File or Ctrl +F

Yes. Next question please.

For your information, these symptoms are also related with this bug:

Topic: System Language settings crash Nepomuk and Strig:

http://kubuntuforums.net/forums/inde...opic=3110547.0


Nepomuk/strigi crashes or refuses to work correctly with some languages (probably because of some special characters like éöüğşç - just a guess though), if those languages are set as system-wide/deafult locale. One workaround for this bug is to set system wide language to English. I filed this bug long ago, but it is not fixed yet (at least, not in KDE 4.4)

Oooh, nice. I was afraid kfind had been tossed-out. I'll put that back in the menu & wait for KDE to fix their new toy.

Re: Is Nepomuk (search in Dolphin) completely useless?

Might be a silly question, but do you have Desktop Search turned on and configured?

K > System Settings > Advanced > Desktop Search
Basic Settings tab:
Enable Nepomuk Semantic Desktop and Strigi Desktop File Indexer - are they checked?

File Indexing tab:
Strigi Index Folders
Have you checked the folders you want indexed? If you want removable media included in the indexing, have you checked Index Files on Removable Media?

Re: Is Nepomuk (search in Dolphin) completely useless?

What version of KDE SC are you using?. In the case you are in 4.4.4, there is a problem with libsoprano that could be related to this. This has already been reported:

https://bugs.launchpad.net/ubuntu/+s...no/+bug/590088

The last post indicates that this is solved in soprano 2.4.3.

Any one knows if that is that version is going to be backported?

Re: Is Nepomuk (search in Dolphin) completely useless?

@beetle: Soprano? Nepomuk is using Virtuoso these days.

Re: Is Nepomuk (search in Dolphin) completely useless?

So, then, why: dmesg | grep -i nepomuk is reporting this?:

and also seems to be happening in the bug report I pasted in my previous post.

Re: Is Nepomuk (search in Dolphin) completely useless?

By the way, it seems that virtuoso is the backend for Soprano. Maybe you meant soprano/sesame

[Vistaus]

Re: Is Nepomuk (search in Dolphin) completely useless?

Yeah, I guess I meant that
