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