Perhaps you should try some spelling variations:
der reformen » der reform
reformen de » reformen der, reformen des, reformen die
anhang der » anhand der, anhang dr, anhang die
de david » die david, wade david, dawe david
qian yi » qian yan
david n » david a, david _, david k
wang » wing, wan

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 OR lang) yan) OR (qian yi)) anhang der reformen de david n w ;~.
• Adding a wildcard symbol may retrieve word variants: (((wang or lang) yan) or (qian yi)) anhang der reformen de david n w ;*.
