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