Hmm... that's a bug.
What notmuch *should* be doing here is taking as the subject of the
thread the subject of the first message in the thread that matched,
(rather than the subject of the first message in the thread).
The thread_create has all that information, (it constructs two
lists---one of all its messages, and one of matched messages).
Now the next step is still missing. Let's say that instead of 2/3
mesages matched in the thread, (and by the way, did you all now that
that's what's being reported there? it's not the number of unread
messages or anything like that, but the number of matched
messages). Anyway, let's say you had something like 1/20 there
instead. And let's also assume that there aren't any unread messages in
Then when you go to view that thread you will see all the messages open,
and you won't have any information as to which message matched. What
*should* happen here is that only the messages that matched should be
open, and the messages that didn't match should be closed. Currently,
the various pieces of the system don't have access to the information
they need for this result. One way to do it would be to make "notmuch
search" return a list of message IDs rather than a thread ID and then
emacs could pass that list to "notmuch show". Alternately, the emacs
interface could pass the current thread ID to "notmuch show" but also
pass along the search string and then "notmuch show" could indicate
which messages matched the search.
Another thing to decide is how this relates with the default behavior of
opening unread messages but closing read messages. Would possibility
there could be to make that work just like any other search, just as I
described above. If we were to go that route, I think it might mean
getting rid of the distinction between "inbox" and "unread", and I'm not
sure I want to do that or not.
Anyway, I'd love to hear some ideas.

Hopefully, the fix of displaying the subject from the first matched
message would help here.
