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