Perhaps you should try some spelling variations:
fiendens » findens, fiennes, pendens, tiendens, fienens, diendens
fienes » fiennes, dienes, bienes
fiende" » tiende", fiene", diende", finde"
fiend" » find", fien", tiend"
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 ((fiend" OR field") or frend"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(fiendens or fienes) (fiende\" or ((fiend\" OR field\") or frend\"))*".
• Removing quotes may allow a broader search: (fiendens or fienes) (fiende or ((fiend OR field ) or frend ))*.
