Perhaps you should try some spelling variations:
"wit:bon vivant" » "whit:bon vivant", "wait:bon vivant", "wit:born vivant", "wit:bono vivant", "wit:bone vivant"
"witt:bond vivant" » "whitt:bond vivant", "waitt:bond vivant", "witt:bornd vivant", "witt:bonod vivant", "witt:boned vivant", "pitt:bond vivant", "litt:bond vivant", "witt:band vivant", "witt:bono vivant", "witt:boyd vivant"
"wikt:tono vivant" » "wik:tono vivant", "wilt:tono vivant", "wikt:torno vivant", "wikt:otono vivant", "wikt:todo vivant"

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

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