Perhaps you should try some spelling variations:
doing seine » doing science
seine daten » keine daten, seiten daten, seine dauer
where son » where sun, where do, where you
yang jie » yang jui, yang yi, yang jun
yang jin » yang jun, ying jin, shang jin
daten 2 » daten 5, daten b, daten 1
2 where » 4 where
yang xi » yang yi, yang jui
son i » von i, son _, con i

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: doing seine daten 2 where son i ((((yang jie) OR (yang jin))) or (((yang di) or (yang xi)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doing seine daten 2 where son i ((((yang jie) OR (yang jin))) OR (((yang di) OR (yang xi)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doing seine daten 2 where son i ((((yang jie) OR (yang jin))) or (((yang di) or (yang xi)))) ;*".
