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