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