Perhaps you should try some spelling variations:
"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wik:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bond vivant"
"wikt:biondo vivant" » "witt:biondo vivant", "wit:biondo vivant", "wik:biondo vivant", "wikt:bidondo vivant", "wikt:biondi vivant", "wikt:brondo vivant"
"wikt:mono vivant" » "witt:mono vivant", "wit:mono vivant", "wik:mono vivant", "wikt:modo vivant", "wikt:mano vivant", "wikt:mino 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: "((\"wikt:bon vivant\") OR (((\"wikt:biondo vivant\") OR (\"wikt:mono vivant\"))))~".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wikt:biondo vivant ) OR ( wikt:mono vivant ))))~.
• Adding a wildcard symbol may retrieve word variants: (("wikt:bon vivant") OR ((("wikt:biondo vivant") OR ("wikt:mono vivant"))))*.
