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