• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hua) OR (feng juan)) shang hai ren ((sang minh) OR (song min)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hua) or (feng juan)) shang hai ren ((sang minh) OR (song min)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hua) or (feng juan)) shang hai ren ((sang minh) OR (song min)) cong shu ;*.
