Perhaps you should try some spelling variations:
fiendens » findens, fiennes, fienes, fienens, diendens, kiendens, fieldens, frendens
bienen » dienen, tienen, bedienen
fiende" » fiene", diende", kiende", fielde", finde", frende"
fiend" » field", find", frend"
tiende" » entiende"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(fiendens or (bienen or viennese)) ((fiende\" OR fiend\") or tiende\")".
• Removing quotes may allow a broader search: (fiendens or (bienen or viennese)) ((fiende OR fiend ) or tiende ).
• Adding a wildcard symbol may retrieve word variants: "(fiendens or (bienen or viennese)) ((fiende" OR fiend") or tiende")*.
