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