Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wik:bon vivant", "wilt:bon vivant", "wikt:born vivant", "wikt:bond vivant", "wikt:bone vivant"
"wit:bono vivant" » "wit:borno vivant", "wit:bondo vivant", "wit:boneo vivant", "whit:bono vivant", "witt:bono vivant", "wait:bono vivant", "wit:mono vivant", "wit:cono vivant"
"wit:tono vivant" » "whit:tono vivant", "witt:tono vivant", "wait:tono vivant", "wit:torno vivant", "wit:otono vivant", "wit:todo 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 ((("wit:bono vivant") OR ("wit:tono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wit:bono vivant\") OR (\"wit:tono vivant\"))))".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wit:bono vivant ) OR ( wit:tono vivant )))).
• Adding a wildcard symbol may retrieve word variants: (("wikt:bon vivant") OR ((("wit:bono vivant") OR ("wit:tono vivant"))))*.
