• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((werner von) OR (werkes von)) siemens (((ringoe\\" OR rgingoe\\") OR ingoe\\") OR ing\\")\"".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens (((ringoe OR rgingoe ) OR ingoe ) OR ing ).
