A simple shell way to do this would be notmuch search-tags | grep "^bremner\." | xargs -I {} notmuch search tag:{} That's pretty quick over a fair amount of messages. It would be quicker, I imagine, if it did the grepping inside of a program, but this is still way down there in the subsecond range. NB. I don't have that many tags, so maybe the grepping step would bog down a bit if I had more. But I doubt someone would have that much more than a few hundred.
