bug? notmuch earch doesn't search threads

[Jason Woofenden]

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?
