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