Activity search behaves strangely with dash in search term

Created by: mwilck

Searching for "suse-module-tools" in my activity list, I get a bunch of false matches:

It seems to match with the SUSE category name. Still I find this rather not intuitive with the search term "suse-module-tools". I'm currently running hamster e6b90fcd, which doesn't differ from 3.0.2 in any significant way for this problem, AFAICS.

(Those black bars look strange as well, but that's just a nitpick).
