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"
"fink:bon vivant" » "fink:born vivant", "fink:bono vivant", "fink:bond vivant", "fin:bon vivant", "link:bon vivant", "find:bon vivant"
"fink:bone vivant" » "fink:borne vivant", "fink:bonoe vivant", "fink:bonde vivant", "fin:bone vivant", "link:bone vivant", "find:bone vivant", "fink:one vivant", "fink:pone vivant", "fink:done 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 ((("fink:bon vivant") OR ("fink:bone vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"fink:bon vivant\") OR (\"fink:bone vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( fink:bon vivant ) OR ( fink:bone vivant ))))*.
