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