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", "winkt:bon vivant"
"wik:bon vivant" » "wik:born vivant", "wik:bono vivant", "wik:bond vivant", "wink:bon vivant"
"wick:bon vivant" » "wick:born vivant", "wick:bono vivant", "wick:bond vivant", "nick:bon vivant", "dick:bon vivant", "rick:bon vivant"
"wik:band vivant" » "wink:band vivant", "wik:banda vivant", "wik:bank vivant", "wik:hand 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 ((((("wik:bon vivant") OR ("wick:bon vivant"))) OR ("wik:band vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((((\"wik:bon vivant\") OR (\"wick:bon vivant\"))) OR (\"wik:band vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((((( wik:bon vivant ) OR ( wick:bon vivant ))) OR ( wik:band vivant ))))*.
