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

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 "indeterminacy") OR ("determinar" OR "determine")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"determinacy\" or \"indeterminacy\") or (\"determinar\" OR \"determine\"))".
• Removing quotes may allow a broader search: (( determinacy or indeterminacy ) or ( determinar OR determine )).
• Adding a wildcard symbol may retrieve word variants: (("determinacy" or "indeterminacy") or ("determinar" OR "determine"))*.
