• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong ((((yang hua) OR (yang hui))) OR (ying hua)) rain yan ((jiu congo) OR (du congo)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((((yang hua) or (yang hui))) or (ying hua)) rain yan ((jiu congo) OR (du congo)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yang hua) or (yang hui))) or (ying hua)) rain yan ((jiu congo) OR (du congo)) shu ;*.
