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