Perhaps you should try some spelling variations:
zeng » eng, feng, peng
sehen » gehen
zehend » gehend, zehen, behend
zehnd » zehn, zahnd, zehnt
zend » end, tend, send
gehenden » gehende, angehenden, gehorenden

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: (zeng OR (sehen OR ((zehend OR (zehnd OR zend)) OR gehenden))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(zeng or (sehen or ((zehend or (zehnd OR zend)) or gehenden)))".
• Adding a wildcard symbol may retrieve word variants: (zeng or (sehen or ((zehend or (zehnd OR zend)) or gehenden)))*.
