Perhaps you should try some spelling variations:
fiendens » findens, pendens, tendens, fieldens, fienens, tiendens
fienes » dienes, bienes, tienes
fiennes » viennese
fiend" » field", fien", tiend"
find" » fund"
frend" » trend", fremd", freed"
freud" » fraud"

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