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