Perhaps you should try some spelling variations:
"german-speaking proper" » "german-speaking peoples", "german-speaking people", "german-speaking europe", "germany-speaking proper"
"german-speaking power" » "german-making power", "german-taking power", "german-speaking code", "germany-speaking power"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"german-speaking proper\") OR (\"german-speaking power\"))".
• Removing quotes may allow a broader search: (( german-speaking proper ) OR ( german-speaking power )).
• Adding a wildcard symbol may retrieve word variants: (("german-speaking proper") OR ("german-speaking power"))*.
