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