• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang yan)) wuhan china chang pan ((di song) OR (kim song)) (star OR stay) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yan)) wuhan china chang pan ((di song) OR (kim song)) (star or stay) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yan)) wuhan china chang pan ((di song) OR (kim song)) (star or stay) ;*.
