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