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", "liut:bono vivant", "list:bono vivant", "litt:mono vivant", "litt:cono vivant", "litt:tono vivant"
"lita:bono vivant" » "lita:borno vivant", "lita:bondo vivant", "lita:boneo vivant", "lita:mono vivant", "lita:cono vivant", "lita:tono vivant", "lista:bono vivant", "lima:bono vivant", "lisa:bono 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 ("lita:bono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"litt:bono vivant\") OR (\"lita:bono vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( litt:bono vivant ) OR ( lita:bono vivant ))))*.
