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