Perhaps you should try some spelling variations:
doing sin » dong sin, doing un, doing von
sin daten » seine daten, von daten, die daten
where so » where do, here so, where you
yang jin » yang jie, yang jun, ying jin
daten 2 » daten 5, daten b, daten 1
2 where » 4 where
yang xi » yang yi, yang jui
so i » so im, so mi, son i

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: doing sin daten 2 where so i ((yang jin) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing sin daten 2 where so i ((yang jin) or (((yang di) or (yang xi)))) ;*.
