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