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
yang jin » yang jie, yang jun, ying jin
yang yun » yang jun, tang yun, yang yue
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 ((yang jin) OR (yang xi)) ((yang yun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: move using data bias chen ((yang jin) or (yang xi)) ((yang yun) or (yang di)) ;*.
