Like I said earlier. I think that's a bug we should report to the Xapian
folks.

Meanwhile, it just occurred to me that we can make "notmuch search not
tag:inbox" work without any change to Xapian.

For every document we store in the database we put a special term on it
to indicate its type. (We mostly just have documents of type "mail" but
we also have documents of type "timestamp"---see the comment at the top
of lib/database.cc for details.)

So if we take the string "not tag:inbox" and turn it into "type:mail and
not tag:inbox" then that will work just fine. (That's close to what
we're doing currently, but different. Right now we try to parse the
query "not tag:inbox" on its own and then combine the result with
another query generated from a term representing the "mail" type.)
