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