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