• If you are trying to use Boolean operators, they must be ALL CAPS: ((liang sun) OR (dong sin)) ((((yan guan) OR (yang yang))) OR (nan yan)) yang jie kang kong sar ;~.
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (dong sin)) ((((yan guan) or (yang yang))) or (nan yan)) yang jie kang kong sar ;*.
