• If you are trying to use Boolean operators, they must be ALL CAPS: ((werner von) OR (werkes von)) siemens ((ring OR ringo ) OR ((fgingeo OR fingo ) OR ing ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((werner von) OR (werkes von)) siemens ((ring OR ringo ) OR ((fgingeo OR fingo ) OR ing ))~".
• Adding a wildcard symbol may retrieve word variants: ((werner von) OR (werkes von)) siemens ((ring OR ringo ) OR ((fgingeo OR fingo ) OR ing ))*.
