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