• Performing a fuzzy search may retrieve terms with similar spellings: ((((((dong yang) OR (wang yang))) or (wang yong))) or (dong bin)) ya hua brain yan jiu cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((dong yang) OR (wang yang))) OR (wang yong))) OR (dong bin)) ya hua brain yan jiu cong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((dong yang) OR (wang yang))) or (wang yong))) or (dong bin)) ya hua brain yan jiu cong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((((((dong yang) OR (wang yang))) or (wang yong))) or (dong bin)) ya hua brain yan jiu cong shu ;*.
