• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((wang yang) OR (((yang xi) OR (yang jun)))) jin chang zhang jin song van ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((wang yang) or (((yang xi) or (yang jun)))) jin chang zhang jin song van ;*.
