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