I have no idea. Maybe it was caused by not used hashed_unique?

Probably there are no problems with sorting. This test will be obtain
information about what is the approximately cost of converting
std::strings to QStrings. but I still do not have this numbers as I am
preparing to push some more commits (probably not ready for merge,
cause there are still lack of docs, but it is something "usable")

I will be refactoring filters later today and try to incorporate your
comments and proposals
