I've heretofore presumed (and correct me if I'm wrong) that it is acceptable to do both/and. IOW, I will sometimes append additional material, in square brackets, after the complete and correct title. My thinking is that this can make relavant articles easier to locate in searches. For example I might post an article titled "Special Forces Deployed" as "Special Forces Deployed [Scud Hunt, Iraq]".
I sometimes do the same thing. It doesn't affect the FR search function a bit, so long as you keep the original title.
