Perhaps you should try some spelling variations:
"bestimmungen allgemeine" » "bestimmung allgemeiner", "storungen allgemeine", "verbindungen allgemeine"
"abbildungen allgemeines" » "abbildungen allgemeine", "abbildungen allgemeiner", "verbindungen allgemeines"

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