Perhaps you should try some spelling variations:
"wikt:bon vivant" » "wit:bon vivant", "wikt:born vivant", "wikt:bond vivant", "wikt:bona vivant", "wikt:bon vivan"
"witt:bone vivant" » "witt:borne vivant", "witt:bonde vivant", "witt:bonae vivant", "witt:bone vivan", "hitt:bone vivant", "wit:bone vivant", "witt:one vivant", "witt:pone vivant", "witt:done vivant"
"wait:borno vivant" » "wait:borno vivan", "want:borno vivant", "walt:borno vivant", "whit:borno vivant", "wait:torno vivant", "wait:born vivant", "wait:corno 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 ((("wait:borno vivant") OR ("witt:bone vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wait:borno vivant\") OR (\"witt:bone vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wait:borno vivant ) OR ( witt:bone vivant ))))*.
