Perhaps you should try some spelling variations:
fiendens » findens, pendens, tendens, fiendns, fienens, diendens
fiendns » fiendish
fienes » dienes, bienes, tienes
fiennes » viennese
fiende" » fiend", fiene", diende"
tiende" » entiende"

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 fiendns) OR (fienes OR fiennes)) (fiende" or tiende").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((fiendens or fiendns) or (fienes OR fiennes)) (fiende\" or tiende\")".
• Removing quotes may allow a broader search: ((fiendens or fiendns) or (fienes OR fiennes)) (fiende or tiende ).
• Adding a wildcard symbol may retrieve word variants: "((fiendens or fiendns) or (fienes OR fiennes)) (fiende" or tiende")*.
