• The words AND, OR and NOT may confuse the search; try adding quotes: "wang zhang ((ying eu) or (ying hua)) cost sharing risk ((hong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang zhang ((ying eu) or (ying hua)) cost sharing risk ((hong shu) OR (wong shiu)) ;*.
