tonga eiu » kong eiu
yan wang » yuan wang, yang yang, qian wang
wang yue » wong yue, wang hua, wang he
yang jin » yang jie, ying jin, shang jin

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan wang yue cheng ((yang jin) OR (yang jun)) ((cong shu) OR (((tonga eiu) OR (dong bin)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan wang yue cheng ((yang jin) or (yang jun)) ((cong shu) or (((tonga eiu) or (dong bin)))) ;*.
