• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"german ((ethnicity relations) OR (ethnic relations)).\\") or (\\"german ethnicity question.\\"))\"".
• Removing quotes may allow a broader search: (( german ((ethnicity relations) OR (ethnic relations)). ) or ( german ethnicity question. )).
