• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuhan) OR (wang yan)) ((wang jing) OR (wang ning)) shen chang ming hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuhan) or (wang yan)) ((wang jing) OR (wang ning)) shen chang ming hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuhan) or (wang yan)) ((wang jing) OR (wang ning)) shen chang ming hong ghi ;*.
