Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
kang minah » sang minh
yang yang » wang yang, wang yan
gene kang » gene bank
duong anh » dang anh, duong van, trong anh
yi human » i human, ii human, 2 human
cong seo » hong seo, cong shu, von seo
cong sun » cong shu, cong van, wing sun
yang yi » yang di, yang xi, yang jui

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: yang yang yi human gene kang minah ((((cong seo) OR (cong sun))) OR (duong anh)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang yi human gene kang minah ((((cong seo) or (cong sun))) or (duong anh)) ;*.
