• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang wang) OR (wang liang))) OR (wang yong)) yan hua ren ((yan jiu) OR (yang jin)) long shu ;.

• Adding a wildcard symbol may retrieve word variants: ((((wang wang) OR (wang liang))) or (wang yong)) yan hua ren ((yan jiu) or (yang jin)) long shu ;*.
