wang yao » wang yan, gang yao, wang tao
yang yao » yang yang, wang yan, yang yi
yang jui » yang judy, yang di, yang xi
jui gene » i gene, iii gene, jui meng
jae song » jae yong, jie song, jae young

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yao) OR (yang yao)) yang jui gene bank ((jae song) OR (((kim song) OR (kim eung)))) ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yao) or (yang yao)) yang jui gene bank ((jae song) or (((kim song) OR (kim eung)))) ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yao) or (yang yao)) yang jui gene bank ((jae song) or (((kim song) OR (kim eung)))) ghi ;*.
