chen yang » chen rong
pen yang » pei yang, dan yang, ren yan
kim tong » kim song, kim dong, kim jong
tong hui » wang hui
nan ya » nan yan, nana yaa
et a » et al, et la, e a

• If you are trying to use Boolean operators, they must be ALL CAPS: ((nan ya) OR (((dong yang) OR (dong hoang)))) et a ((pen yang) OR (chen yang)) kim tong hui ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nan ya) or (((dong yang) or (dong hoang)))) et a ((pen yang) OR (chen yang)) kim tong hui ;*".
