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