If the set of possible entries is finite (and reasonably small), then
you can use :visible, but otherwise :filter is most likely the way to go.

:filter should be run often enough (or even more often than that, in my
experience), so if it's not often enough for you, please report the
precise case where it fails to be (re)run.
