Perhaps you should try some spelling variations:
dene » den, denk, deng
denne » deine, dene, wenne, danne
donne » done
dense » sense
meine » seine, keine
denn » den, wenn, dann

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: ((dene OR (((denne OR donne) OR dense) OR meine)) OR denn).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dene or (((denne OR donne) or dense) or meine)) or denn)".
• Adding a wildcard symbol may retrieve word variants: ((dene or (((denne OR donne) or dense) or meine)) or denn)*.
