Perhaps you should try some spelling variations:
"witt:bon vivant" » "pitt:bon vivant", "litt:bon vivant", "witt:born vivant", "witt:bono vivant", "witt:bond vivant"
"wik:bon vivant" » "wik:born vivant", "wik:bono vivant", "wik:bond vivant", "wick:bon vivant"
"wink:bon vivant" » "wink:born vivant", "wink:bono vivant", "wink:bond vivant", "link:bon vivant", "fink:bon vivant", "wind:bon vivant"
"wikt:cono vivant" » "wit:cono vivant", "wilt:cono vivant", "wikt:con vivant", "wikt:como vivant", "wikt:mono vivant", "wickt:cono vivant"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("witt:bon vivant") OR ("wikt:cono vivant"))) OR ((("wik:bon vivant") OR ("wink:bon vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"witt:bon vivant\") OR (\"wikt:cono vivant\"))) OR (((\"wik:bon vivant\") OR (\"wink:bon vivant\"))))*".
• Removing quotes may allow a broader search: (((( witt:bon vivant ) OR ( wikt:cono vivant ))) OR ((( wik:bon vivant ) OR ( wink:bon vivant ))))*.
