What is baloo_file_extractor and why is it humping my hard drive?

to get back to baloo replacing Nepomuk: there is a known bug where some get 
disk access problems.

Otherwise it seems that is far less resouce-chewing and in many ways "*nix" in 
KISS rather than what, from an outsider perspective, seemed to be a slightly 
overambitious approach to search abilities.

to me it boils down to: who in the name of all possible higher powers do 
really sit and "tag" their files? So far I know noone who does and that 
includes me.

why: usercase. Let me use my dearly beloved wife. She throws everything she 
likes on the "desktop" (a kubuntu user) and then use either Dolphin, Digikam  
or a music player (normally Clementine) to find what she has saved/downloaded. 
She does not use tags, has actually never heard of the concept, does not have 
desktop search switched on (my decision) as she never uses/used it in any 
case.

And she is not unique, she is actually a very normal user.

Given that in Dolphin I can still not find a way to search for tagged files 
without writing some cryptic "baloosearch" line, yea that would make my wife 
or sons go ecstatic. 

This turned into a rant, when I was actually meaning to say that baloo seems 
way better than nepomuk. Still there are many improvements in practical use to 
be made and one would be a "tag searcher" in Dolpin if tags are ever going to 
be useful.
