Perhaps you should try some spelling variations:
zeng » eng, feng, peng
sehen » gehen
zehend » gehend, behend, sehend
zehen » gehen
zehnd » zend, zahnd, zehnt
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 zehen) OR (zehnd OR zehn)) OR gehenden))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(zeng or (sehen or (((zehend OR zehen) or (zehnd or zehn)) or gehenden)))".
• Adding a wildcard symbol may retrieve word variants: (zeng or (sehen or (((zehend OR zehen) or (zehnd or zehn)) or gehenden)))*.
