Perhaps you should try some spelling variations:
"bildern allgemeine" » "bayern allgemeine", "bildung allgemein", "deren allgemeine"
"felder allgemeine" » "feld allgemeine", "fehler allgemeiner", "filter allgemeines"
"akute allgemeine" » "die allgemeine", "eine allgemeine", "e allgemeine"

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: (((("bildern allgemeine") OR ("felder allgemeine"))) OR ("akute allgemeine")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"bildern allgemeine\") OR (\"felder allgemeine\"))) or (\"akute allgemeine\"))".
• Removing quotes may allow a broader search: (((( bildern allgemeine ) OR ( felder allgemeine ))) or ( akute allgemeine )).
• Adding a wildcard symbol may retrieve word variants: (((("bildern allgemeine") OR ("felder allgemeine"))) or ("akute allgemeine"))*.
