Perhaps you should try some spelling variations:
seine dauer » einer dauer, seine daten, seine water
sin dauer » die dauer, i dauer
where do » where _
yang jie » yang jin, yang jui, yang xi
2 where » 4 where
yang yi » yang xi, yang jui
do fdi » does fdi
dong » doing, long, done

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: dong ((sin dauer) OR (seine dauer)) 2 where do fdi ((yang jie) OR (((yang di) OR (yang yi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((sin dauer) OR (seine dauer)) 2 where do fdi ((yang jie) or (((yang di) or (yang yi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((sin dauer) OR (seine dauer)) 2 where do fdi ((yang jie) or (((yang di) or (yang yi)))) ;*.
