[Feature request] make search respect the selected category

[Biergartenparadoxon]

eg. there is a ton of packages to update but one can't be installed (corrupt or whatever)
It's not possible to search for the one package, deselect it and hit update again.
Tho it is possible to deselect it after a search, you have to go back, select update again wait for the check etc.

or eg. to ckeck what qt related packages are installed without having to scroll thru a massive list of uninstalled packages after searching for qt.
