Perhaps you should try some spelling variations:
fiendens » findens, fiennes, pendens, fieldens, frendens
frentes » frente, rentes
fienes » fiennes, dienes, bienes
fielde" » fielded", fielden", fielder"
fiend" » field", find", frend"

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 frentes) OR fienes) (fielde" or fiend").
• Removing quotes may allow a broader search: ((fiendens or frentes) or fienes) (fielde or fiend ).
• Adding a wildcard symbol may retrieve word variants: "((fiendens or frentes) or fienes) (fielde" or fiend")*.
