Perhaps you should try some spelling variations:
fiendens » findens, fiennes, pendens, fieldens, fienens
fienes » fiennes, dienes, bienes
tienes » tienen, dienes, bienes
fiend" » field", find", fien"
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 tienes) or viennese)) (fiend" OR (frend" or freud")).
• Removing quotes may allow a broader search: (fiendens or ((fienes or tienes) or viennese)) (fiend or (frend or freud )).
• Adding a wildcard symbol may retrieve word variants: "(fiendens or ((fienes or tienes) or viennese)) (fiend" or (frend" or freud"))*.
