Perhaps you should try some spelling variations:
fiendens » findens, fienes, pendens, fieldens, fienens, tiendens
tienes » tienen, dienes, bienes
fiennes » viennese
fiend" » field", fien", tiend"
find" » fund"
frend" » trend", freud", fremd"

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 (tienes or fiennes)) ((fiend\" OR find\") or frend\")".
• Removing quotes may allow a broader search: (fiendens or (tienes or fiennes)) ((fiend OR find ) or frend ).
• Adding a wildcard symbol may retrieve word variants: "(fiendens or (tienes or fiennes)) ((fiend" OR find") or frend")*.
