Searching Macros

Something like this would be nice:
Search macros are chunks of a search that you can reuse in multiple places, including saved and ad hoc searches. Search macros can be any part of a search, such as an eval statement or search term, and do not need to be a complete command. You can also specify whether or not the macro field takes any arguments.

It would be awesome if we could do this, it might help enforce better searching behaviour amongst our more careless users too...
