• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((werner von) OR (wirken von)) siemens (((rginge\\" OR rggggingeoe\\") OR rggingoo\\") OR ing\\")*\"".
• Removing quotes may allow a broader search: ((werner von) OR (wirken von)) siemens (((rginge OR rggggingeoe ) OR rggingoo ) OR ing )*.
