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