• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens (((rging" OR rging") OR (rgingee" OR ringoeee")) OR ing")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens (((rging\" OR rging\") OR (rgingee\" OR ringoeee\")) OR ing\")*".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens (((rging OR rging ) OR (rgingee OR ringoeee )) OR ing )*.
