Well the first thing on my list I've managed to solve quite quickly as it
turned out in the end.
I ran strigidaemon from konsole and it reported
Resource temporarily unavailable
strigi.daemon: Daemon cannot run: the file /home/oliverthered/.strigi/lock is
locked.
(this was even though strigiclient seemed to work ok and there was no
strigidaemon processes running)
so I removed the lock file and it started ok
so I killed it and started it as
strigidaemon& from konsole
Then I went in to try the desktop search setting again, and still it was
showing as not running, even though it was.
So clicked and un clicked a lot,,, no change
then I ran nepomukserver in the same konsole, which said it was running (even
though I had it unchecked and had applied the settings in desktopn search
settings)
so I killed it and ran it from the konsole
went back into desktop search settings and still didn't look good, played
around with a few things and some stuff came up on the konsole.

so now I went to look for that time in tmp
cat /tmp/virtuoso_k27921.ini
but it wasn't there.
So I created a tmpory directory in my ~/foobar and cd'd into it
then tried clicking on the desktop search settings, clicking nepomuk on and off
and on again and clicking apply and noted the file number changed by the
/tmp/vitruoso bit stayed the same.
so then tried to
cp /tmp/virtuoso* .
lots of times
whilst clicking nepomuk off and on and apply
but then found that it wouldn't copy
so
done the same again as sudo
eventually got a copy of the file, which was owned by root
-rw------- 1 root root 987 2011-01-07 22:57 virtuoso_k27936.ini
sudo cat then told me:

virtuoso-temp.trx
and loads of other settings that hopefully are in a file somewhere I can edit
so that I can change what it does to my own taste?
andhow, so I checked in that directory
ls
/home/oliverthered/.kde/share/apps/nepomuk/repository/main/data/virtuosobackend/
and there was nothing unexpected there so moved it to .bak
done the desktop search settings off and on and applied, and hey presto it
worked well partly..
so now I've got a nice nepomuk strigi file indexer icon on my system tray and
I click on it, only to find that even though strigiclinet had made a nice big
index all of it's own no files where listed as currently indexed.
So I left it and I've now got a 3.4Gib size store indexing 1448 files.
So heopfully it's all now working nicely, after a bit of buggeration and I've
got some stuff lurking around to clean up I expect
So i don't know if this issue has been fixed or not, but it would be nice if
when things didn't work there was a nice little report or something giving me
a clue as to why they didn't work and even nicer offering the option to fix it.
It would also be nice to have the option to trash the old database etc... from
the GUI (for people like my mum and partner) or back-it up etc... so that the
desktop search can be started a fresh if there are any issues. or deleted to
clean out several gigs of space.
some warning about the transaction log and ability to delete it would be the
least I suppose.
anyhow, going to have a bit more of a play around with this. Setting up esay
sharing of indexes between users would be nice or multiple database files so
that they can be linked etc... though I should imagine it's network
transparent or something, being in the users home directory would make that a
bit odd though.
Anyhow, going to have a bit more of a play around, and check to see if every
user on the machine is going to have to index all the mp3 and other media files
I've got, and ever network user too. or if we can share them and only have a
little index of our own for our own personal data.
(The indexer started again with a clean store and now my store size is 51.3MiB
with 2,326 files indexed. it wwas GiB half way through writing this.
So bug report on the way, I may have a look at a fix, or atleast making it
easier to work out what's going on in the future and possibly not removing the
configuration files from tmp if the start-up failes.
Thanks,
Oliver Stieber.
