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