• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yuhuan huang) OR (yuan wang)) ((hua zhen) OR (hua zhong)) zhang minh hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yuhuan huang) or (yuan wang)) ((hua zhen) OR (hua zhong)) zhang minh hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yuhuan huang) or (yuan wang)) ((hua zhen) OR (hua zhong)) zhang minh hong ghi ;*.
