Yes, that's a fine idea.

Currently, notmuch doesn't implement this behavior but relies on
Xapian's query parser to do so. As such, I'd really prefer to see
Xapian's documentation augmented here before we start documenting
any particular behavior in notmuch.

Olly, is the above list of operators complete and in the correct order
of  precendence?
