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