Perhaps you should try some spelling variations:
"witt:bon vivant" » "pitt:bon vivant", "litt:bon vivant", "witt:born vivant", "witt:bond vivant", "witt:bone vivant"
"wikt:bono vivant" » "wikt:borno vivant", "wikt:bondo vivant", "wikt:boneo vivant", "wit:bono vivant", "wik:bono vivant", "wilt:bono vivant", "wikt:mono vivant", "wikt:cono vivant", "wikt:tono vivant"
"wikt:borndo vivant" » "wit:borndo vivant", "wik:borndo vivant", "wilt:borndo vivant", "wikt:bordo vivant", "wikt:borneo vivant", "wikt:borrando vivant"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"witt:bon vivant\") OR (((\"wikt:bono vivant\") OR (\"wikt:borndo vivant\"))))~".
• Removing quotes may allow a broader search: (( witt:bon vivant ) OR ((( wikt:bono vivant ) OR ( wikt:borndo vivant ))))~.
• Adding a wildcard symbol may retrieve word variants: (("witt:bon vivant") OR ((("wikt:bono vivant") OR ("wikt:borndo vivant"))))*.
