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