• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yao) OR (yang di)) ((((yang hua) OR (yang hui))) OR (ying hua)) rene han yan cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yao) or (yang di)) ((((yang hua) OR (yang hui))) or (ying hua)) rene han yan cong shu ;*".
