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