I had noticed this long back, and very sad that I forgot about this when I
reached home :( The next time I realized that was after the release,
nevertheless I've requested for a feature to allowing to disable that here
https://bugs.kde.org/show_bug.cgi?id=283605 . It should be a pretty easy
one, adding a config option.

#ccc solid;padding-left:1ex;"> Hi all, 
after using PA1 for a couple of days productively (for reading 
scientific papers while on the train), I noticed some effects of our 
heavy reliance on Nepomuk that I think we need to find a workaround for 
in PA2, namely startup and indexing. 
 
1. The fact that it takes a very long time until file resources are 
available after boot is quite annoying, especially since there is no 
indication why the&#39;re not there. 
As a user not knowing how Nepomuk works, I would freak out every time I 
boot and my carefully configured activities all seem to be empty except 
for plasmoids. And I&#39;d freak out even more if I tried to re-add the 
resources only to find that they are seemingly gone (!). 
Being someone who does know only very little about Nepomuk and Strigi, I 
ask myself: Why does it take so long to get the files ready on every 
boot? Shouldn&#39;t they only have to be indexed once and then be instantly 
ready? 
So we need to either 
1. Get resources that have already been indexed ready much faster on 
subsequent boots (much preferred if possible in any way) 
2. Show a placeholder at activities where resources are connected which 
are not ready yet, indicating they need to be loaded first 
The current situation will create a lot of confusion for novice users 
and quite some annoyance for advanced users (the device is practically 
unusable for the first few minutes if your activity is based mainly on 
documents or pictures) 
 
2. Take a probably very common usecase: I use my device (of course not 
plugged to a socket since it&#39;s a mobile device) and I get a new file 
from the internet or a usb stick (the latter won&#39;t happen for novices in 
PA1 since there is no file browser, but in PA2 we&#39;ll have one). I want 
to connect it to an activity, but it doesn&#39;t show up. 
I remember that there was something about indexing, so I wait. And wait. 
And wait. And wonder why it&#39;s still not there. 
True story: After trying several things to get my damn files indexed 
(including deleting the nepomuk database but except plugging the device 
in, since I was on the train and then at work where I don&#39;t carry my 
adaptor) I finally resorted to deleting the .kde folder. Which, in turn, 
got me into _serious_ trouble ;) 
Long story short: It is a problem that new files won&#39;t get indexed 
without mains power because Strigi is suspended, again causing lots of 
confusion for users who don&#39;t have pretty deep knowledge of Nepomuk and 
Strigi. </blockquote><div> I had noticed this long back, and very sad that I \
