• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong nan) OR (dong yang))) OR (dong di)) ya hua rein yan jiu long shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong nan) OR (dong yang))) or (dong di)) ya hua rein yan jiu long shu ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong nan) OR (dong yang))) or (dong di)) ya hua rein yan jiu long shu ;*.
