Perhaps you should try some spelling variations:
dan » dank (Expand Search), dahn (Expand Search), dann (Expand Search)
dannk » danknk (Expand Search), dahnnk (Expand Search), dannnk (Expand Search), dank (Expand Search), dann (Expand Search)
leiner\" » kleiner\" (Expand Search), meiner\" (Expand Search), seiner\" (Expand Search), leinr\" (Expand Search)
eine\" » ein\" (Expand Search)
einer\" » einr\" (Expand Search)
einen\" » einn\" (Expand Search), seinen\" (Expand Search), meinen\" (Expand Search), eines\" (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 dannk) OR das) OR den) ((leiner\\" OR eine\\") OR (deren\\" OR (einer\\" OR einen\\")))\"".
• Removing quotes may allow a broader search: (((dan OR dannk) OR das) OR den) ((leiner OR eine ) OR (deren OR (einer OR einen ))).
