Perhaps you should try some spelling variations:
ann » anne
danne » dannee, danner, dance, donne
dannee » danneee, dannere, dancee, donnee, danneel, dannele, annee
anna » annea, anne
erkannten » erkanneten, erkannte, anerkannten, bekannten

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: (( (ann OR (danne OR dannee)) OR anna ) OR ( erkannten OR has )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (ann or (danne OR dannee)) or anna ) or ( erkannten or has ))".
• Adding a wildcard symbol may retrieve word variants: (( (ann or (danne OR dannee)) or anna ) or ( erkannten or has ))*.
