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