Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
wan hyoung » wang hyoung, man houng, min hyoung
hong yeon » jeong yeon, hong seo, hong een
aii test » ai test, api test, ein test
ii test » ai test, i test, api test
kan min » han min, kian ming, kyaw min
myeon » myeong, myron, pyeon

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung yang ((aii test) OR (ii test)) kan min ((hong yeon) OR (dong myeon)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung yang ((aii test) or (ii test)) kan min ((hong yeon) or (dong myeon)) ;*.
