Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
wang ying » wang yong, wang jing, wang ning
wang yang » wang yan, wang liang, wang yanling
yang ai » yang di, yang xi, yang yi
ai test » api test, i test, ii test
a mine » _ mine, a mini, a mile
a min » a main, a mini, a mind

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