• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (hong kong))) OR (dong bin)) ((ya a) OR (et a)) chen yu ca along du ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (hong kong))) or (dong bin)) ((ya a) or (et a)) chen yu ca along du ;*.
