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