• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"gebet von siemens ring\") OR (((\"weber von siemens ging\") OR (\"wieder von siemens ing\"))))*".
• Removing quotes may allow a broader search: (( gebet von siemens ring ) OR ((( weber von siemens ging ) OR ( wieder von siemens ing ))))*.
