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