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