human gene » human genome, human gender, human bone
can turn » can return, a turn, ein turn
anh tuan » anh tran, dinh tuan, oanh tran
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
wong sau » wong sam, wong siu, wong shiu
yan jiu » pang jiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang ((can turn) or (anh tuan)) human gene ((yan jiu) or (((yang jin) OR (yang jie)))) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((can turn) OR (anh tuan)) human gene ((yan jiu) OR (((yang jin) OR (yang jie)))) wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((can turn) or (anh tuan)) human gene ((yan jiu) or (((yang jin) OR (yang jie)))) wong sau ;".
• Adding a wildcard symbol may retrieve word variants: lang ((can turn) or (anh tuan)) human gene ((yan jiu) or (((yang jin) OR (yang jie)))) wong sau ;*.
