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