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