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