Perhaps you should try some spelling variations:
changes made » changes a, changes due
yi changes » ii changes, iii changes, 2 changes
yang yang » wang yang, wang yan
song thin » song shin, song jin, song min
yan yang » yao yang, tan yang, yan wang
dan yang » daun yang, tan yang, wang yang
qi yi » qin yi, li yi

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: wan ((((yan yang) OR (yang yang))) OR (dan yang)) qi yi changes made ((wong lai) OR (song thin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan ((((yan yang) or (yang yang))) or (dan yang)) qi yi changes made ((wong lai) or (song thin)) ;*.
