• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang tang) OR (wang yan)) yang yun li yong cai ((fang cheng) OR (huang cheng)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang tang) or (wang yan)) yang yun li yong cai ((fang cheng) OR (huang cheng)) ;*".
