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