Perhaps you should try some spelling variations:
"witt:bon vivant" » "pitt:bon vivant", "litt:bon vivant", "witt:born vivant", "witt:bono vivant", "witt:bond vivant", "whitt:bon vivant", "waitt:bon vivant"
"wikt:boneo vivant" » "wikt:borneo vivant", "wikt:bonoeo vivant", "wikt:bondeo vivant", "wik:boneo vivant", "wilt:boneo vivant", "wikt:bono vivant", "wikt:bonet vivant", "wikt:oneo vivant", "wikt:poneo vivant", "wikt:doneo vivant"
"wit:bone vivant" » "wit:borne vivant", "wit:bonoe vivant", "wit:bonde vivant", "whit:bone vivant", "wait:bone vivant", "wit:one vivant", "wit:pone vivant", "wit:done 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:boneo vivant\") OR (\"wit:bone vivant\"))))~".
• Removing quotes may allow a broader search: (( witt:bon vivant ) OR ((( wikt:boneo vivant ) OR ( wit:bone vivant ))))~.
• Adding a wildcard symbol may retrieve word variants: (("witt:bon vivant") OR ((("wikt:boneo vivant") OR ("wit:bone vivant"))))*.
