• If you are trying to use Boolean operators, they must be ALL CAPS: ((chen wang) OR (chen ping)) ((((yang xi) OR (yang jui))) OR (yang di)) cheng han xin jong a ;~.
• Adding a wildcard symbol may retrieve word variants: ((chen wang) or (chen ping)) ((((yang xi) or (yang jui))) or (yang di)) cheng han xin jong a ;*.
