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: "\"\\"\\\"(dan OR (mann OR kann)) ((leiner\\\" OR (einer\\\" OR seiner\\\")) OR (seine\\\" OR eine\\\"))*\\"\"".
• Removing quotes may allow a broader search: \ (dan OR (mann OR kann)) ((leiner\ OR (einer\ OR seiner\ )) OR (seine\ OR eine\ ))*.
