Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
mun seung » mun leong, mun young
api test » ai test, ii test
kaw mun » kyaw min
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 ((api test) OR (i test)) kaw mun seung yeon ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang ((api test) or (i test)) kaw mun seung yeon ;*.
