Perhaps you should try some spelling variations:
fiendens » findens, fiennes, pendens, tiendens, fienens, diendens, fieldens
fienes » fiennes, dienes, bienes
fiende » tiende, fiene, diende, fielde, finde
fiend » field, find, fien
frend » trend, freud, fremd

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: (( (fiendens OR fienes) fiende ) OR ( (fiendens OR fienes) (fiend OR frend) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (fiendens OR fienes) fiende ) or ( (fiendens OR fienes) (fiend or frend) ))".
• Adding a wildcard symbol may retrieve word variants: (( (fiendens OR fienes) fiende ) or ( (fiendens OR fienes) (fiend or frend) ))*.
