Perhaps you should try some spelling variations:
dan » dahn (Expand Search), dann (Expand Search), dans (Expand Search)
danns » dahnns (Expand Search), dannns (Expand Search), dansns (Expand Search), dann (Expand Search), dans (Expand Search), hanns (Expand Search)
dank » dahnk (Expand Search), dannk (Expand Search), dansk (Expand Search)
dask » dass (Expand Search)
denn » den (Expand Search), wenn (Expand Search), dein (Expand Search)
seinen » seine (Expand Search)
seiner » einer (Expand Search), meiner (Expand Search), seine (Expand Search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((dan OR (danns OR das)) OR (dank OR dask)) OR (hahn OR denn)) (seinen OR seiner )~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((dan OR (danns OR das)) OR (dank OR dask)) OR (hahn OR denn)) (seinen OR seiner )~".
• Adding a wildcard symbol may retrieve word variants: (((dan OR (danns OR das)) OR (dank OR dask)) OR (hahn OR denn)) (seinen OR seiner )*.
