• The words AND, OR and NOT may confuse the search; try adding quotes: "((weiter von) OR (wiesel von)) siemens (((((ring OR ringo) OR ringo) OR ringoo) OR rging) OR ing)~".
• Adding a wildcard symbol may retrieve word variants: ((weiter von) OR (wiesel von)) siemens (((((ring OR ringo) OR ringo) OR ringoo) OR rging) OR ing)*.
