• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"werner von siemens fingo\") OR (((\"weiber von siemens ging\") OR (\"werkes von siemens ing\"))))~".
• Removing quotes may allow a broader search: (( werner von siemens fingo ) OR ((( weiber von siemens ging ) OR ( werkes von siemens ing ))))~.
• Adding a wildcard symbol may retrieve word variants: (("werner von siemens fingo") OR ((("weiber von siemens ging") OR ("werkes von siemens ing"))))*.
