Perhaps you should try some spelling variations:
fiendens » findens, fiennes, fienes
dienden » dienen, tienden, diende
bienen » dienen, tienen, bedienen
frend" » trend", freud", fremd"
tiende" » entiende"

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 dienden) OR (bienen OR viennese)) (frend" or tiende").
• Removing quotes may allow a broader search: ((fiendens or dienden) or (bienen or viennese)) (frend or tiende ).
• Adding a wildcard symbol may retrieve word variants: "((fiendens or dienden) or (bienen or viennese)) (frend" or tiende")*.
