Perhaps you should try some spelling variations:
changes made » changes a, changes due
jin changes » main changes, run changes, jin chang
made doing » made using, matrade doing, made housing
doing von » doing un, ing von
yang tan » yang fan, yang yang, liang tan
ruan jin » ruan ji, huan jie
dean » dewan, jean, den

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: wang ((yang tan) OR (yang dean)) ruan jin changes made doing von ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang tan) or (yang dean)) ruan jin changes made doing von ;*.
