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