Perhaps you should try some spelling variations:
"kowatscher heimatbucher der" » "batschkaer heimatbucher der" (Expand Search), "kowatscher heimatbuch der" (Expand Search), "kowatscher heimatbucher ii" (Expand Search), "kowatscher heimatbucher band" (Expand Search)
"kowatscher heimatbuch uber" » "kowatscher heimatbuch der" (Expand Search)
"batschka heimat der" » "batschka heimat die" (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: "((\"batschka heimat der\") OR (((\"kowatscher heimatbucher der\") OR (\"kowatscher heimatbuch uber\"))))~".
• Removing quotes may allow a broader search: (( batschka heimat der ) OR ((( kowatscher heimatbucher der ) OR ( kowatscher heimatbuch uber ))))~.
• Adding a wildcard symbol may retrieve word variants: (("batschka heimat der") OR ((("kowatscher heimatbucher der") OR ("kowatscher heimatbuch uber"))))*.
