Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wik:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bond vivant"
"wilt:bon vivant" » "wilt:born vivant", "wilt:bono vivant", "wilt:bond vivant", "walt:bon vivant", "wild:bon vivant", "witt:bon vivant"
"wilf:bon vivant" » "wilf:born vivant", "wilf:bono vivant", "wilf:bond vivant", "wolf:bon vivant", "wild:bon vivant"
"wick:bon vivant" » "wick:born vivant", "wick:bono vivant", "wick:bond vivant", "nick:bon vivant", "dick:bon vivant", "rick: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: (((("wikt:bon vivant") OR ((("wilt:bon vivant") OR ("wilf:bon vivant"))))) OR ("wick:bon vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wikt:bon vivant\") OR (((\"wilt:bon vivant\") OR (\"wilf:bon vivant\"))))) OR (\"wick:bon vivant\"))*".
• Removing quotes may allow a broader search: (((( wikt:bon vivant ) OR ((( wilt:bon vivant ) OR ( wilf:bon vivant ))))) OR ( wick:bon vivant ))*.
