• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan liang jia cheng zhang qian ((cong sun) or (((wing ian) OR (wing tan)))) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan liang jia cheng zhang qian ((cong sun) or (((wing ian) OR (wing tan)))) ;*.
