Huh, I tried this a couple months ago with a more complicated query,
like:

thread:{from:bob or from:jane}

and I remember notmuch barking at me about spaces or the "or" or
something -- anyway I got the impression that it couldn't accept
multi-part queries inside the "thread:{}" syntax. But looking at your
patch maybe I just needed to quote differently?

Anyway I'll give this a test this weekend. It would be *very* nice if we
could use this syntax rather than the ugly home-grown one.

Thanks for the report!

Right, notmuch has this unusual " -> "" quoting thing.

Let me know the results of your test, and if it's also continuing to
work for me by then, I'll install the change.  Thanks for taking a look.

I am not sure whether this is relevant, but I give a shot...

I tried the following queries from command line:

$ notmuch search 'thread:"{from:bob or from:jane}"'

thread:0000000000000b91   2009-01-20 [6/6] ...
thread:00000000000015fa   2008-11-26 [2/2] ...

and

$ notmuch search 'from:bob or from:jane}':

thread:0000000000000b91   2009-01-20 [1/6] ...
thread:00000000000015fa   2008-11-26 [1/2] ...


The outer '':s protect from shell expansion so what is
inside those goes verbatim to notmuch and from there to
xapian query parser (IIRC). 

Former includes all messages in thread where at least
one message matched to the query and latter just those
messages that match the query.

Like Sean mentioned in another message, Xapian converts ""
to " in query string (probably something irrelevant in this
discussion) the thread:"{...}" syntax binds the whole expression
to this thread: prefix (Why {...} is not enough is beyond me ;D)
