Perhaps you should try some spelling variations:
first kann » first kind
one first » come first, one fast, one fits
dong ping » dong sin, dong bin, dong jung
kann von » kann man, kann ein, bonn von
yang jui » yang judy, yang xi
wong yue » wang yue, hong yu
yang yi » yang xi

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: one first kann von cohen ((((yang jui) OR (dong ping))) OR (yang yi)) ((wong yue) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one first kann von cohen ((((yang jui) or (dong ping))) or (yang yi)) ((wong yue) or (yang di)) ;*.
