Oh, and there is also `nix-env -qa` thing, that lists all the available
packages.
It has `-P` flag that tells it to print attribute paths. Combined with grep
this lets you find what you need:

% nix-env -qaP | grep kdepim
nixos.pkgs.kde4_prev.kdepim
kdepim-4.10.5
nixos.pkgs.kde4.kdepim
kdepim-4.11.5
nixos.pkgs.kde4_next.kdepim
kdepim-4.12.2
...

Yes, that takes some time. I don't know if there exists a faster way to
search nix expressions, probably, unfortunately, not.
