Perhaps you should try some spelling variations:
"schriften der management" » "schriften power management", "schriften cancer management", "schriften des management", "anschriften der management", "schriften zur management"
"schriften kmu management" » "schriften icu management", "schriften du management", "schriften zu management", "schriften im management", "schriften des management"
"schriften ii management" » "schriften iii management", "schriften _ management", "schriften zu management", "schriften des management"

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: (("schriften kmu management") OR ((("schriften ii management") OR ("schriften der management"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"schriften kmu management\") or (((\"schriften ii management\") OR (\"schriften der management\"))))*".
• Removing quotes may allow a broader search: (( schriften kmu management ) or ((( schriften ii management ) OR ( schriften der management ))))*.
