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