• The words AND, OR and NOT may confuse the search; try adding quotes: "wan qian yan jiang ((chen aizheng) OR (chen zheng)) rong ((tong shui) or (tong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan qian yan jiang ((chen aizheng) OR (chen zheng)) rong ((tong shui) or (tong hui)) ;*.
