Perhaps you should try some spelling variations:
done using » line using, move using
using dfas » using dbs, using dcs, using ddms
yang yang » wang yang, wang yan
dfas 4.3 » dfas 7.3, bias 4.3, cfcs 4.3
4.3 when » 4.1 when, 9.3 when, 2.4.3 when
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
when so » when do, when co, when soft
so ging » so fing

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 dfas 4.3 when so ging ((((yang yang) OR (yang jie))) OR (((yang jui) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: done using dfas 4.3 when so ging ((((yang yang) or (yang jie))) or (((yang jui) or (yang di)))) ;*.
