• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((weber von) OR (werkes von)) siemens ((rginge\\" OR (ringee\\" OR ringeoe\\")) OR ing\\")*\"".
• Removing quotes may allow a broader search: ((weber von) OR (werkes von)) siemens ((rginge OR (ringee OR ringeoe )) OR ing )*.
