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