Perhaps you should try some spelling variations:
fiendens » findens, fiennes, fienes, tiendens, fiendns, fienens
bienes » bienen, dienes
fiende » tiende, fiend, fiene
frend » trend, freud, fremd
find » fund

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