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