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