• Performing a fuzzy search may retrieve terms with similar spellings: (("wilf:bon vivant") OR ((("wit:bono vivant") OR ("wit:borno vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wilf:bon vivant\") OR (((\"wit:bono vivant\") OR (\"wit:borno vivant\"))))".
• Removing quotes may allow a broader search: (( wilf:bon vivant ) OR ((( wit:bono vivant ) OR ( wit:borno vivant )))).
• Adding a wildcard symbol may retrieve word variants: (("wilf:bon vivant") OR ((("wit:bono vivant") OR ("wit:borno vivant"))))*.
