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