• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (((wang yong) OR (wang yang))))) OR (dong sign)) ya hua rein yan jiu cong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) or (((wang yong) OR (wang yang))))) or (dong sign)) ya hua rein yan jiu cong shu ;".
