Perhaps you should try some spelling variations:
dan » dank (Expand Search), dahn (Expand Search), dann (Expand Search)
seines\\" » eines\\" (Expand Search), seiner\\" (Expand Search), seinen\\" (Expand Search), meines\\" (Expand Search), seins\\" (Expand Search)
seine\\" » eine\\" (Expand Search), meine\\" (Expand Search), sein\\" (Expand Search)
deinen\\" » seinen\\" (Expand Search), meinen\\" (Expand Search), einen\\" (Expand Search)
deiner\\" » einer\\" (Expand Search), meiner\\" (Expand Search), seiner\\" (Expand Search)

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 hahn) ((seines\\\" OR seine\\\") OR (deinen\\\" OR deiner\\\"))\\"\"".
• Removing quotes may allow a broader search: \ (dan OR hahn) ((seines\ OR seine\ ) OR (deinen\ OR deiner\ )).
