Perhaps you should try some spelling variations:
song thin » song shin, song jin
gene yang » gene bank
wang tao » wang qiao, huang tao, wang yan
yang jui » yang di, yang yi
yang kim » yong kim, kang kim, hyung kim
song min » song ming, gong min, jong min
yang xi » yang di, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang tao ((((yang jui) or (yang judy))) or (yang xi)) gene yang kim ((song thin) OR (song min)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang tao ((((yang jui) OR (yang judy))) OR (yang xi)) gene yang kim ((song thin) OR (song min)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang tao ((((yang jui) or (yang judy))) or (yang xi)) gene yang kim ((song thin) OR (song min)) ;*".
