• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan liang jia ((cheng zhang) OR (cheng han)) qian ((cong sun) OR (wing ian)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan liang jia ((cheng zhang) OR (cheng han)) qian ((cong sun) or (wing ian)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan liang jia ((cheng zhang) OR (cheng han)) qian ((cong sun) or (wing ian)) ;*.
