Perhaps you should try some spelling variations:
dann » kann, dans, ann
danner » kanner, danser, anner, manner, tanner, wanner
banner » manner, tanner
anna » anne
kannten » kannte, bekannten, erkannten

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: (( (dann OR (danner OR banner)) OR anna ) OR ( kannten OR has ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (dann or (danner OR banner)) or anna ) or ( kannten or has ))*".
