Perhaps you should try some spelling variations:
fiendens » findens, fienes, tendens, fieldens, fienens
pendens » pendent, pendants
dienes » dienen, diener
fiennes » viennese
fiend" » field", find", fien"
frend" » freud", fremd", freed"

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 pendens) or (dienes or fiennes)) (fiend" OR (frend" or trend")).
• Removing quotes may allow a broader search: ((fiendens or pendens) or (dienes or fiennes)) (fiend or (frend or trend )).
• Adding a wildcard symbol may retrieve word variants: "((fiendens or pendens) or (dienes or fiennes)) (fiend" or (frend" or trend"))*.
