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