I added tag:me to all messages from me. Then I added this to my index page: tag:notmuch and tag:unread and tag:me So my attention could be drawn to threads I'd participated in, which had new messages. (This list has enough traffic that I won't always keep up). It didn't work though. I assume because no single message has all those tags. (The ones with tag:me lack tag:unread and maybe tag:notmuch.) If this is not a bug, and you want it to only find messages that match, and not threads that match, then I make this feature request: I want a way to do the above: to search for threads that have the tags I'm looking for (but not necessarily all in the same message within the thread.) The vim ui is exclusively thread-based, and the notmuch manpage says it's thread-based... I want thread-based searching! :) Thanks, - Jason P.S. I submitted (my first) 6 patches to this list on Monday, and have not gotten a reply or seen them merged. Is there something more I should do, or should I just be patient?
