baloofilerc

DESCRIPTION
I don't use plasma search functions so baloo normally does it's thing and I
mostly do not interfere until I notice inordinary disk IO.


STEPS TO REPRODUCE
0. Have "only basic indexing=true" in baloofilerc. My understading is this
enables filename indexing only.
1. Delete large directory with photos (a dataset, say 15000 images), I don't
know if this triggered baloo. I suspect it did.
2. Notice constant writing to disk (~60 MiB/s), confirmed its baloo via iotop,
check with fatrace its to baloo index

OBSERVED RESULT
Index has grown to 54 GB

             MTimeDB:       8.80 MiB     2.173 %


EXPECTED RESULT
Have a smaller index file and not spend so much work on indexing filenames.
