Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
kin seung » kim eung, kin keong
test awt » test auf
wan yan » wang yan, nan yan, wai yan
yang li » yang lin, yang xi, tang li
yang yi » yang xi, yang jui
test a » test _, test 4, test 5

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan ((((yang di) or (yang li))) or (yang yi)) ((test awt) OR (test a)) kin seung yeon ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((((yang di) OR (yang li))) OR (yang yi)) ((test awt) OR (test a)) kin seung yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((yang di) or (yang li))) or (yang yi)) ((test awt) OR (test a)) kin seung yeon ;*".
