Perhaps you should try some spelling variations:
"german external relations." » "german internal regulations.", "german external positions.", "germany internal relations.", "term external relations."
"german ethnic question." » "german ethnicity question.", "german ethical question.", "german ethnicity questions."
"german topic question." » "german civic question.", "german town question.", "germany top question."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("german external relations.") or ((("german topic question.") OR ("german ethnic question."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("german external relations.") OR ((("german topic question.") OR ("german ethnic question."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"german external relations.\") or (((\"german topic question.\") OR (\"german ethnic question.\"))))*".
• Removing quotes may allow a broader search: (( german external relations. ) or ((( german topic question. ) OR ( german ethnic question. ))))*.
