• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((ringo" OR (rgingeo" OR rginge")) OR (fing" OR ing"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens ((ringo\" OR (rgingeo\" OR rginge\")) OR (fing\" OR ing\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ringo OR (rgingeo OR rginge )) OR (fing OR ing )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((ringo" OR (rgingeo" OR rginge")) OR (fing" OR ing"))*.
