Perhaps you should try some spelling variations:
move using » done using
using data » missing data
data bias » data base, data big, dataset bias
bias chen » bias when
yong jin » yang jin, ying jin, song jin
yang jun » yang jui, pang jun, yang jin
yang xi » 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: move using data bias chen ((yong jin) OR (yang xi)) ((yang jun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: move using data bias chen ((yong jin) or (yang xi)) ((yang jun) or (yang di)) ;*.
