• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong wang human brain ((((yan jiu) OR (((yang jie) OR (yang di))))) OR (yang jin)) yong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong wang human brain ((((yan jiu) or (((yang jie) OR (yang di))))) or (yang jin)) yong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong wang human brain ((((yan jiu) or (((yang jie) OR (yang di))))) or (yang jin)) yong shu ;*.
