Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung youn
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
seung won » seung joon, seung youn, myung won
api test » i test, ii test
ai test » i test, ii test, ein test
kaw mun » kyaw min

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