• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang ning) OR (wang yang)) ye ((a rein) OR (a region)) ryangg jie zhang yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ning) or (wang yang)) ye ((a rein) OR (a region)) ryangg jie zhang yu ;*".
