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