Perhaps you should try some spelling variations:
done using » line using, move using
using rnas » using arenas, using real, using rs
wang yang » wang yan, wang liang, wang yanling
rnas 4.3 » areas 4.3, bias 4.3, dfas 4.3
4.3 when » 4.1 when, 9.3 when, 2.4.3 when
yang jin » yang jie, yang jun, ying jin
when so » when do, when co, when soft
so ging » so fing
yang yi » yang xi, 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 rnas 4.3 when so ging ((((wang yang) OR (yang jin))) OR (((yang yi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: done using rnas 4.3 when so ging ((((wang yang) or (yang jin))) or (((yang yi) or (yang di)))) ;*.
