Perhaps you should try some spelling variations:
allgemeineneres » allgemeinere, allgemeineren, allgemeinerer
allgemeineres » allgemeinere, allgemeineren, allgemeinerer
allgemeineseren » allgemeineren, allgemeinere, allgemeinsten

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: bildung ((allgemeine OR (allgemeineneres OR allgemeineres)) OR allgemeineseren).
• The words AND, OR and NOT may confuse the search; try adding quotes: "bildung ((allgemeine or (allgemeineneres OR allgemeineres)) or allgemeineseren)".
• Adding a wildcard symbol may retrieve word variants: bildung ((allgemeine or (allgemeineneres OR allgemeineres)) or allgemeineseren)*.
