Perhaps you should try some spelling variations:
"wikt:bon vivant" » "wit:bon vivant", "wik:bon vivant", "wilt:bon vivant", "wikt:born vivant", "wikt:bond vivant", "wikt:bone vivant"
"witt:bono vivant" » "witt:borno vivant", "witt:bondo vivant", "witt:boneo vivant", "pitt:bono vivant", "litt:bono vivant", "witt:mono vivant", "witt:cono vivant", "witt:tono vivant"
"wait:borno vivant" » "waite:borno vivant", "walt:borno vivant", "want:borno vivant", "wait:borneo vivant", "wait:torno vivant", "wait:born 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:bono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wait:borno vivant\") OR (\"witt:bono vivant\"))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wait:borno vivant ) OR ( witt:bono vivant ))))*.
