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