• If you are trying to use Boolean operators, they must be ALL CAPS: wang qian ((((yan han) OR (kang han))) OR (yan zhang)) en chang ((tin hong) OR (thi hong)) ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian ((((yan han) OR (kang han))) or (yan zhang)) en chang ((tin hong) or (thi hong)) ghi ;*".
