• If you are trying to use Boolean operators, they must be ALL CAPS: ((((doing sin) OR (dong sin))) OR (wang yan)) ((ye a) OR (e a)) chen yang tin wong yue ;.
• Adding a wildcard symbol may retrieve word variants: ((((doing sin) or (dong sin))) or (wang yan)) ((ye a) or (e a)) chen yang tin wong yue ;*.
