Perhaps you should try some spelling variations:
fiendens » findens, pendens, tendens, tiendens, fiendns, fienens
fienes » dienes, bienes, tienes
fiennes » viennese
fiende" » tiende", fiend", fiene"
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 OR fiennes)) (fiende" or frend").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(fiendens or (fienes OR fiennes)) (fiende\" or frend\")".
• Removing quotes may allow a broader search: (fiendens or (fienes OR fiennes)) (fiende or frend ).
• Adding a wildcard symbol may retrieve word variants: "(fiendens or (fienes OR fiennes)) (fiende" or frend")*.
