Most of the time, the the results provided by search do not have labels.
Once Central is opened, it returns the same results, but sometimes when you close&reopen central it cannot find quickstarts it could found previously and vice versa.
For example right now, I have two instances of JBT/JBDS openew with central and searching for "greeter" in one results in no quickstarts found and in the second one finds just one quickstart - "jboss-greeter". After closing and reopening Central in the instance, which previously has shown "jboss-greeter", when seached for "greeter", now it finds some another quickstart named "greeter".

I couldn't find any determinism in this behaviour.

I can see no errors in error log, nor any error dialog.

Sometimes, when I click on the found quickstart, new quickstart wizard is shown, sometimes nothing happens (again, no error anywhere).

I have tried it on JBT 4.3.0.Beta1 on Fedora 22 with GTK3/GTK2, JBDS 9.0.0.Beta1 on Fedora 22 with GTK2/3 and on Windows 8.1 on JBDS 9.0.0.Beta1.
