• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang shiyong) or (wang yang)) yang ((dean cost) OR (debt cost)) savings risk wrong when ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang shiyong) or (wang yang)) yang ((dean cost) OR (debt cost)) savings risk wrong when ;*.
