• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan ((zhang rui) OR (zhang hui)) tan yang ka ((long thanh) OR (luong thanh)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan ((zhang rui) or (zhang hui)) tan yang ka ((long thanh) OR (luong thanh)) ;*".
