• If you are trying to use Boolean operators, they must be ALL CAPS: ((liang sun) OR (dong bin)) roa juan ((meng duan) OR (meng hsuan)) jin song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang sun) or (dong bin)) roa juan ((meng duan) OR (meng hsuan)) jin song shin ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (dong bin)) roa juan ((meng duan) OR (meng hsuan)) jin song shin ;*.
