• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((dan yang) OR (yang yang))) OR (wang yang))) OR (dong sin)) ya hua chen yan thang cong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((((dan yang) or (yang yang))) or (wang yang))) or (dong sin)) ya hua chen yan thang cong shu ;*.
