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