Perhaps you should try some spelling variations:
"wikt:bon vivant" » "wit:bon vivant", "wilt:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bone vivant", "wickt:bon vivant", "winkt:bon vivant"
"witt:bon vivant" » "witt:born vivant", "witt:bono vivant", "witt:bone vivant", "pitt:bon vivant", "litt: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 ("witt:bon vivant"))) OR ("wik:bond vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wikt:bon vivant\") OR (\"witt:bon vivant\"))) OR (\"wik:bond vivant\"))".
• Removing quotes may allow a broader search: (((( wikt:bon vivant ) OR ( witt:bon vivant ))) OR ( wik:bond vivant )).
• Adding a wildcard symbol may retrieve word variants: (((("wikt:bon vivant") OR ("witt:bon vivant"))) OR ("wik:bond vivant"))*.
