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