Perhaps you should try some spelling variations:
mean using » plan using, meaning using
human gene » human genome, human gender, human bone
san using » plan using, win using, zen using
gene yang » gene bank
yang yang » wang yang, wang yan
wong shiu » wong siu, cong shu, song shin
long ago » long arm

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: ((mean using) OR (san using)) data human gene yang yang ((long ago) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mean using) OR (san using)) data human gene yang yang ((long ago) or (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((mean using) OR (san using)) data human gene yang yang ((long ago) or (wong shiu)) ;*.
