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