Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wik:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bond vivant"
"wikt:boneo vivant" » "witt:boneo vivant", "wit:boneo vivant", "wik:boneo vivant", "wikt:borneo vivant", "wikt:bonoeo vivant", "wikt:bondeo vivant", "wikt:bono vivant", "wikt:bone vivant"
"wikt:done vivant" » "witt:done vivant", "wit:done vivant", "wik:done vivant", "wikt:donde vivant", "wikt:one vivant", "wikt:don vivant"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wikt:boneo vivant\") OR (\"wikt:done vivant\"))))~".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wikt:boneo vivant ) OR ( wikt:done vivant ))))~.
• Adding a wildcard symbol may retrieve word variants: (("wikt:bon vivant") OR ((("wikt:boneo vivant") OR ("wikt:done vivant"))))*.
