Perhaps you should try some spelling variations:
think wenn » think we
last think » last thing, last things
wang yang » wang yan, wang liang, wang yanling
daun yang » dan yang, tan yang, un yang
wenn dann » wenns dann, wenn das, wenn man
ying jin » yang jin, yang jie
dann bin » dong bin

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: ((wang yang) OR (((daun yang) OR (du yang)))) ((ying jin) OR (jing ji)) last think wenn dann bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((daun yang) or (du yang)))) ((ying jin) OR (jing ji)) last think wenn dann bin ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((daun yang) or (du yang)))) ((ying jin) OR (jing ji)) last think wenn dann bin ;*.
