Perhaps you should try some spelling variations:
"anwendungen allgemeines" » "anwendungen allgemeine", "anwendung allgemeine", "trennungen allgemeines"
"abbildungen allgemeine" » "verbindungen allgemeine", "verbindungen allgemeines", "uberlegungen allgemeine"

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: (("abbildungen allgemeine") OR ("anwendungen allgemeines"))*.
• Removing quotes may allow a broader search: (( abbildungen allgemeine ) or ( anwendungen allgemeines ))*.
