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