Comment:

 I think I agree that this is the better option:

 {{{
 Xapian::Query(((B中:(pos=1) AND B中文:(pos=1) AND B文:(pos=1)) OR
                (S中:(pos=2) AND S中文:(pos=2) AND S文:(pos=2))))
 }}}

 This case seems more analogous to a phrase search, which we handle more
 like that:

 {{{
 >>> print(qp.parse_query('"hello world"'))
 Query(((Bhello at 1 PHRASE 2 Bworld at 2) OR (Shello at 1 PHRASE 2 Sworld at 2)))
 }}}

 Though either would be an improvement.

 Marking for 1.4.x (once fixed there we can consider backporting).
