Perhaps you should try some spelling variations:
fiendens » findens, fienes, tienden, fieldens, fienens
tendens » tendenz, tendons, tendent
pendens » pendent, pendants
bienes » bienen, dienes
fiennes » viennese
fiend" » field", find", fien"
frend" » trend", freud", fremd"

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