Perhaps you should try some spelling variations:
allgemeinere » allgemeiner, allgemeinen, allgemeines
allgemeinse » allgemeinste, allgemeinne, allgemeins
allgemeinsere » allgemeinstere, allgemeinnere, allgemeinsre, allgemeiner, allgemeineren, allgemeinste

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 (allgemeinere OR (allgemeinse OR allgemeinsere)))*.
