Update: I forked QCompleter and added full-text search to get quick and 
relatively clean result. Code is in 
calligra/kexi/kexiutils/completer. I gave up with KCompletion for now, it's 
nice class (and has prefix tree) but QCompleter is younger and has better 
model/view concepts.

Who knows maybe Qt5's QCompleter will be improved [Greetings to people that 
made qt-project.org possible!]
