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