Perhaps you should try some spelling variations:
"bildern allgemeine" » "felder allgemeine", "bildung allgemein", "deren allgemeine"
"bayern allgemeine" » "basen allgemeine", "banken allgemeine", "bakterien allgemeine"
"und allgemeines" » "und allgemeine", "7.1 allgemeines", "8.1 allgemeines"

Try widening your search to All Fields.

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: (((("und allgemeines") OR ("2.1 allgemeines"))) OR ((("bayern allgemeine") OR ("bildern allgemeine")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"und allgemeines\") or (\"2.1 allgemeines\"))) or (((\"bayern allgemeine\") OR (\"bildern allgemeine\"))))".
• Removing quotes may allow a broader search: (((( und allgemeines ) or ( 2.1 allgemeines ))) or ((( bayern allgemeine ) OR ( bildern allgemeine )))).
• Adding a wildcard symbol may retrieve word variants: (((("und allgemeines") or ("2.1 allgemeines"))) or ((("bayern allgemeine") OR ("bildern allgemeine"))))*.
