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