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