Perhaps you should try some spelling variations:
allgemein » allgemeines, allgemeiner
allgemeine » allgemeinese, allgemeinere
allgemeinen » allgemeinesen, allgemeineren
allgemeininteresses » allgemeinesinteresses, allgemeinerinteresses, allgemeininteresse, allgemeininteressen, allgemeininteressierte

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