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