• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan yao ((hua chen) OR (yu chen)) chung tong ((young 4) OR (young 5)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan yao ((hua chen) or (yu chen)) chung tong ((young 4) OR (young 5)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan yao ((hua chen) or (yu chen)) chung tong ((young 4) OR (young 5)) ;*.
