• The words AND, OR and NOT may confuse the search; try adding quotes: "werner von siemens (((ring OR (ingo OR ingoo)) OR ((ringoe OR rgingoe) OR rgingooe)) OR ing)~".
• Adding a wildcard symbol may retrieve word variants: werner von siemens (((ring OR (ingo OR ingoo)) OR ((ringoe OR rgingoe) OR rgingooe)) OR ing)*.
