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