A really simple and powerful feature to implement would be the ability to simply alias a search, preceded with a symbol such as, say, !.

For instance, allow a user to save the search @enderio conduit -facade to a quick alias they define called !conduits, @refinedstorage grid -wireless -portable to !grids, and so on.
If the user then wanted to start working on a system that utilises EnderIO conduits and grids, they can simply search !conduits refined | !grids to get the specific items relevant to them without nearly as much typing.
