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