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