• The words AND, OR and NOT may confuse the search; try adding quotes: "yiqian wang yang ((xi gene) or (iii gene)) ((((hong thi) OR (hong ghi))) or (hong hai)) ron paul ;~".
• Adding a wildcard symbol may retrieve word variants: yiqian wang yang ((xi gene) or (iii gene)) ((((hong thi) OR (hong ghi))) or (hong hai)) ron paul ;*.
