Perhaps you should try some spelling variations:
fiendens » findens, tendens, tienden, fieldens, fienens
pendens » pendent, pendants
fienes » dienes, tienes
bienes » dienes
bienen » dienen, tienen, bedienen
diener » dienen
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 pendens) OR (((fienes OR (bienes OR bienen)) OR diener) OR fiennes)) (fiend" or frend")*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((fiendens or pendens) or (((fienes or (bienes OR bienen)) or diener) or fiennes)) (fiend\" or frend\")*".
• Removing quotes may allow a broader search: ((fiendens or pendens) or (((fienes or (bienes OR bienen)) or diener) or fiennes)) (fiend or frend )*.
