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