Perhaps you should try some spelling variations:
zen » zehn
zeng » zehng, eng, feng, peng
zehng » zeheng, zehn, zehnj
zehnt » zehnte, zehn, lehnt
behend » behende, gehend, beheld
gehende » angehende

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: ((zen OR (zeng OR (zehng OR zehnt))) OR (behend OR gehende)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zen or (zeng or (zehng OR zehnt))) or (behend or gehende))".
• Adding a wildcard symbol may retrieve word variants: ((zen or (zeng or (zehng OR zehnt))) or (behend or gehende))*.
