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