This is not currently possible.  Since threads are not stored as
documents in the database, a straightforward implementation would be
linear in the number of threads.  It might be possible to filter the set
of threads to be examined by turning the "AND" query into an "OR" query,
and making a second pass at the thread-id's of messages matching the
expanded query. I'm not sure if/when I'll find time to look at it, but
if someone wants a project, I think most of the xapian pieces are in

"muted" is not something built in to notmuch, so it depends a bit which
hack you're refering to. If you mean the CLI hack described at

     https://notmuchmail.org/excluding/

then yes, the muted tag is propagated.
