Perhaps you should try some spelling variations:
fiendens » findens, fiennes, fienes, fiendns, diendens, kiendens
bienen » dienen, tienen, bedienen
fiende" » fiend", diende", kiende"
fiene" » fienes", fine", tiene"
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 fiene\") or tiende\")".
• Removing quotes may allow a broader search: (fiendens or (bienen or viennese)) ((fiende OR fiene ) or tiende ).
• Adding a wildcard symbol may retrieve word variants: "(fiendens or (bienen or viennese)) ((fiende" OR fiene") or tiende")*.
