• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"german national football team\\") OR (\\"((der nationale) OR (die nationale)) football team\\"))\"".
• Removing quotes may allow a broader search: (( german national football team ) OR ( ((der nationale) OR (die nationale)) football team )).
