Perhaps you should try some spelling variations:
yong yang » dong yang, ying yang, kyoung yang
yang yang » wang yang, wang yan
hong yeon » dong myeon, jeong yeon, hong seo
api test » ai test, ii test
kyaw min » kan min
kaw min » kan min, law main
i test » ai test, i testi, ii test

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: wang ((yong yang) OR (yang yang)) ((api test) OR (i test)) ((kaw min) OR (kyaw min)) hong yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (yang yang)) ((api test) or (i test)) ((kaw min) OR (kyaw min)) hong yeon ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) or (yang yang)) ((api test) or (i test)) ((kaw min) OR (kyaw min)) hong yeon ;*.
