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