Perhaps you should try some spelling variations:
"wilt:bon vivant" » "walt:bon vivant", "wild:bon vivant", "wilf:bon vivant", "wilt:born vivant", "wilt:bono vivant", "wilt:bone vivant"
"wikt:bond vivant" » "wikt:bornd vivant", "wikt:bonod vivant", "wikt:boned vivant", "witt:bond vivant", "wit:bond vivant", "wikt:band vivant", "wikt:bono vivant", "wikt:boyd vivant", "wickt:bond vivant", "winkt:bond vivant"
"wik:bon vivant" » "wik:born vivant", "wik:bono vivant", "wik:bone vivant", "wick:bon vivant", "wink:bon vivant"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("wilt:bon vivant") OR ("wikt:bond vivant"))) OR ("wik:bon vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wilt:bon vivant\") OR (\"wikt:bond vivant\"))) OR (\"wik:bon vivant\"))".
• Removing quotes may allow a broader search: (((( wilt:bon vivant ) OR ( wikt:bond vivant ))) OR ( wik:bon vivant )).
• Adding a wildcard symbol may retrieve word variants: (((("wilt:bon vivant") OR ("wikt:bond vivant"))) OR ("wik:bon vivant"))*.
