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