Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, seung yeon, jeong dahyeon
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
law main » law pain, law making, new main
yang ai » yang di, yang xi, yang yi
ai test » api test, i test, ii test
kaw min » kyaw min, kan 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 ai test ((kaw min) OR (law main)) ((jeong yeon) OR (jeang yean)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang ai test ((kaw min) or (law main)) ((jeong yeon) OR (jeang yean)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang ai test ((kaw min) or (law main)) ((jeong yeon) OR (jeang yean)) ;*.
