• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) wang jing wei ((shen zhang) OR (cheng zhang)) jia ((fang yue) OR (fang yuan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) wang jing wei ((shen zhang) OR (cheng zhang)) jia ((fang yue) or (fang yuan)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) wang jing wei ((shen zhang) OR (cheng zhang)) jia ((fang yue) or (fang yuan)) ;*.
