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