• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((ringo" OR ringe") OR ((inge" 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 ringe\") OR ((inge\" OR fgingee\") OR ing\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ringo OR ringe ) OR ((inge OR fgingee ) OR ing )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((ringo" OR ringe") OR ((inge" OR fgingee") OR ing"))*.
