Perhaps you should try some spelling variations:
done using » line using, move using
hua gene » human gene, a gene, hua ren
gene yan » gene bank, ren yan, see yan
hong hai » shang hai, zhong tai, hong tan
using a » using _
yan tan » tan tan, yan clan, yan guan
a hua » ya hua, _ hua, a hra

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "done using a hua gene yan tan ((hong hai) OR (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: done using a hua gene yan tan ((hong hai) OR (dang hai)) ;*.
