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