Perhaps you should try some spelling variations:
"determinacy" » "determinant", "determinants", "determinante"
"indeterminacy" » "indeterminant", "indeterminants", "indeterminante", "indeterminate"
"determinanten" » "determinants", "determination"

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: (("determinacy" OR "determinanten") OR "indeterminacy").
• Removing quotes may allow a broader search: (( determinacy or determinanten ) or indeterminacy ).
• Adding a wildcard symbol may retrieve word variants: (("determinacy" or "determinanten") or "indeterminacy")*.
