Perhaps you should try some spelling variations:
fiendens » fiennes, pendens, tienden, fieldens, findens, fienens
tendens » tendenz, tendons, tenders
tendent » tendenz, tendency
fienes » fiennes, dienes, bienes
findens » finden, finders, findes
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 (tendens OR tendent)) OR fienes) OR findens) (fiend" OR frend").
• Removing quotes may allow a broader search: (((fiendens or (tendens or tendent)) or fienes) or findens) (fiend OR frend ).
• Adding a wildcard symbol may retrieve word variants: "(((fiendens or (tendens or tendent)) or fienes) or findens) (fiend" OR frend")*.
