Perhaps you should try some spelling variations:
fiendish » fiendishly, fieldish, findish, frendish
wendish » wendisch, wendrich
fienes » fiennes, dienes, bienes
fiend" » field", find", frend"
tiende" » entiende"

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: "((fiendish OR wendish) OR fienes) (fiend" or tiende")*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((fiendish OR wendish) or fienes) (fiend\" or tiende\")*".
• Removing quotes may allow a broader search: ((fiendish OR wendish) or fienes) (fiend or tiende )*.
