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