Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wik:bon vivant", "wikt:born vivant", "wikt:bond vivant", "wikt:bone vivant"
"litt:bono vivant" » "litt:borno vivant", "litt:bondo vivant", "litt:boneo vivant", "pitt:bono vivant", "lita:bono vivant", "liut:bono vivant", "litt:mono vivant", "litt:tono vivant"
"litt:cono vivant" » "pitt:cono vivant", "lita:cono vivant", "liut:cono vivant", "litt:con vivant", "litt:como vivant", "litt:mono vivant"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("wikt:bon vivant") OR ((("litt:bono vivant") OR ("litt:cono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"litt:bono vivant\") OR (\"litt:cono vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( litt:bono vivant ) OR ( litt:cono vivant ))))*.
