Perhaps you should try some spelling variations:
sin dauer » seine dauer, die dauer, i dauer
dauer iii » paper iii, baker iii, dauer ist
iii where » ii where, i where, iii wege
where do » where _
yang jin » yang jie, yang jun, ying jin
yang yi » yang xi, yang jui
do fdi » does fdi

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 OR doing) sin dauer iii where do fdi ((yang jin) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) sin dauer iii where do fdi ((yang jin) or (((yang di) or (yang yi)))) ;*.
