• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (yang xi))) OR (((yang jui) OR (yang yi))))ng y sun chen zhang chin chang ha ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (yang xi))) or (((yang jui) or (yang yi))))ng y sun chen zhang chin chang ha ;*.
