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