Perhaps you should try some spelling variations:
"wit:bon vivant" » "whit:bon vivant", "wait:bon vivant", "wit:born vivant", "wit:bond vivant", "wit:bone vivant"
"witt:bondo vivant" » "whitt:bondo vivant", "waitt:bondo vivant", "witt:borndo vivant", "witt:bonddo vivant", "witt:bonedo vivant", "pitt:bondo vivant", "litt:bondo vivant", "witt:brondo vivant", "witt:biondo vivant", "witt:fondo vivant"
"wikt:bono vivant" » "wikt:borno vivant", "wikt:bondo vivant", "wikt:boneo vivant", "wik:bono vivant", "wilt:bono vivant", "wikt:mono vivant", "wikt:cono vivant", "wikt:tono vivant"

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

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