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