aptitude search '~S~i~Aexperimental'

The narrowing operator ~S is crucial to make sure that the same version
of a package matches both conditions (~i and ~Aexperimental). Without ~S
you would get all packages that are installed and have a version (not
necessarily the installed one) in experimental.

aptitude search '~S~i(~snon-free|~scontrib)'
