Perhaps you should try some spelling variations:
fiendens » findens, tendens, tienden
pendens » pendent, pendants
fienes » dienes, bienes, tienes
fiennes » viennese
frend" » freud", freed", prend"
fremd" » fremde", freud"

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 pendens) or (fienes or fiennes)) ((frend\" OR fremd\") or trend\")".
• Removing quotes may allow a broader search: ((fiendens or pendens) or (fienes or fiennes)) ((frend OR fremd ) or trend ).
• Adding a wildcard symbol may retrieve word variants: "((fiendens or pendens) or (fienes or fiennes)) ((frend" OR fremd") or trend")*.
