Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
jeong wai » leong wai, jeong han, jeong mi
yang yao » yang yang, wang yan, yang yi
bank car » bank card, bank cards, bank a
bank can » banks can, bank card, bank bank
2 human » 3 human
g 2 » g 20, gt 2

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 judy) OR (yang yao))g 2 human gene ((bank car) OR (bank can)) jeong wai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang judy) or (yang yao))g 2 human gene ((bank car) OR (bank can)) jeong wai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang judy) or (yang yao))g 2 human gene ((bank car) OR (bank can)) jeong wai ;*.
