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