I would like to create a "smart search" with a common criteria along
with several uncommon criteria, but I can't seem to figure this out.
Specifically, I colour-tag emails which I consider important, and for
this particular smart-search I want to see any colour-tagged message but
from only a few specific addresses.
Obviously neither "Match all of the follow" nor "Match any of the
following" will work, and "Match all messages" certainly won't do it.
