Perhaps you should try some spelling variations:
dan » dahn (Expand Search), dans (Expand Search)
dank » dahnk (Expand Search), dansk (Expand Search)
dann » dahnn (Expand Search), dansn (Expand Search), mann (Expand Search), kann (Expand Search), denn (Expand Search)
einer" » eine" (Expand Search)
seiner" » seine" (Expand Search), meiner" (Expand Search)
deiner" » deine" (Expand Search), meiner" (Expand Search), leiner" (Expand Search), heiner" (Expand Search)
seines" » eines" (Expand Search), seine" (Expand Search), seinen" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: "(dan OR (dank OR dann)) ((einer" OR seiner") OR (deiner" OR seines"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(dan OR (dank OR dann)) ((einer\" OR seiner\") OR (deiner\" OR seines\"))*".
• Removing quotes may allow a broader search: (dan OR (dank OR dann)) ((einer OR seiner ) OR (deiner OR seines ))*.
