Perhaps you should try some spelling variations:
yang yaong » wang yang, wang yong, yang yao
yang yang » wang yang, wang yan
gene yang » gene bank
han kyung » han kyul, han heung, jin kyung
yang han » yang fan, kang han, yang dean
ya a » a a, ye a, yu a
y a » y la
ghi » nghi, ghia

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yaong) OR (yang yang)) ((ya a) or (y a)) gene yang han kyung ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yaong) OR (yang yang)) ((ya a) OR (y a)) gene yang han kyung ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yaong) OR (yang yang)) ((ya a) or (y a)) gene yang han kyung ghi ;*".
