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