Perhaps you should try some spelling variations:
schwaben vergangenheit » schwabens vergangenheit (Expand Search)
aus schwaben » aus schwabens (Expand Search), die schwaben (Expand Search), aus oberschwaben (Expand Search)
heft 19 » heft 1 (Expand Search), heft 9 (Expand Search)
heft 12 » heft 1 (Expand Search)
heft 10 » heft 1 (Expand Search)
heft 2 » heft 3 (Expand Search), heft 1 (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: "aus schwaben vergangenheit, ((((heft 19) OR (((heft 12) OR (heft 2))))) OR (heft 10))~".
• Adding a wildcard symbol may retrieve word variants: aus schwaben vergangenheit, ((((heft 19) OR (((heft 12) OR (heft 2))))) OR (heft 10))*.
