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