Perhaps you should try some spelling variations:
"wilt:bon vivant" » "walt:bon vivant", "wild:bon vivant", "witt:bon vivant", "wilt:born vivant", "wilt:bond vivant", "wilt:bone vivant"
"wilf:bon vivant" » "wilf:born vivant", "wilf:bond vivant", "wilf:bone vivant", "wolf:bon vivant", "wild:bon vivant"
"wit:bono vivant" » "wit:borno vivant", "wit:bondo vivant", "wit:boneo vivant", "whit:bono vivant", "witt:bono vivant", "wait:bono vivant", "wit:mono vivant", "wit:cono vivant", "wit:tono 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 ("wilf:bon vivant"))) OR ("wit:bono vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wilt:bon vivant\") OR (\"wilf:bon vivant\"))) OR (\"wit:bono vivant\"))".
• Removing quotes may allow a broader search: (((( wilt:bon vivant ) OR ( wilf:bon vivant ))) OR ( wit:bono vivant )).
• Adding a wildcard symbol may retrieve word variants: (((("wilt:bon vivant") OR ("wilf:bon vivant"))) OR ("wit:bono vivant"))*.
