• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (yang jin))) OR (((yang xi) OR (yang yi))))ng a hua chen huang cheng chang c ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (yang jin))) or (((yang xi) or (yang yi))))ng a hua chen huang cheng chang c ;*.
