Perhaps you should try some spelling variations:
sin dauer » seine dauer, die dauer, i dauer
dauer im » dauer iv, dauer iii, dauer ist
im where » rfm where, 2 where, 4 where
where do » where _
yang jun » yang jui, pang jun, yang jin
yang yi » yang xi, yang jui
do 3 » do _, do i, do a
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 im where do 3 ((yang yi) OR (((yang di) OR (((yang judy) OR (yang jun)))))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin dauer im where do 3 ((yang yi) or (((yang di) or (((yang judy) or (yang jun)))))) ;*.
