• If you are trying to use Boolean operators, they must be ALL CAPS: ((((gang yao) OR (yang yao))) OR (wang yan)) wang wei ping yang jin zhong zhi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((gang yao) OR (yang yao))) or (wang yan)) wang wei ping yang jin zhong zhi ;*".
