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