Perhaps you should try some spelling variations:
done using » line using, move using
human bone » human bones, human body
using dcs » using dbs, using ddms, using dhcp
dcs human » das human, des human, does human
tong hui » wang hui
yan jiu » yang jie, yang jin, pang jiu
yang xi » yang di, yang yi, 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: done using dcs human bone ((yan jiu) OR (yang xi)) tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: done using dcs human bone ((yan jiu) or (yang xi)) tong hui ;*.
