Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wilt:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bone vivant", "wickt:bon vivant", "winkt:bon vivant"
"wik:bon vivant" » "wik:born vivant", "wik:bono vivant", "wik:bone vivant", "wick:bon vivant", "wink:bon vivant"
"wik:bond vivant" » "wik:bornd vivant", "wik:bonod vivant", "wik:boned vivant", "wick:bond vivant", "wink:bond vivant", "wik:band vivant", "wik:bono vivant", "wik:boyd 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 ((("wik:bon vivant") OR ("wik:bond vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wik:bon vivant\") OR (\"wik:bond vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wik:bon vivant ) OR ( wik:bond vivant ))))*.
