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