• If you are trying to use Boolean operators, they must be ALL CAPS: doing bin wang yue cheng jing jia ((((wong yue) OR (yang di))) OR (((yang jui) OR (yang july)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing bin wang yue cheng jing jia ((((wong yue) or (yang di))) or (((yang jui) or (yang july)))) ;*.
