I was using (the testversion of) MG and got the hint Did you already know (translated from "Wussten Sie schon?") "In unserer Testversion können Sie Neuerungen schon vor allen anderen ausprobieren." The link behind Testversion doesn't contain the search query I entered. Maybe that would be too much work.

BTW: This hint doesn't make much sense in the testversion, there could be the hint: Thanks for using our testversion. You can also try our stable version.
