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