Perhaps you should try some spelling variations:
allgemeiner » allgemeinen, allgemeines
allgemeinerer » allgemeinener, allgemeineser, allgemeinere, allgemeineren, allgemeinen
allgemeinese » allgemeines, allgemeinere, allgemeinse
allgemeinenere » allgemeinere, allgemeinenen, allgemeinen

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