Perhaps you should try some spelling variations:
"litt:bon vivant" » "pitt:bon vivant", "lita:bon vivant", "liut:bon vivant", "litt:born vivant", "litt:bono vivant", "litt:bone vivant"
"wit:bon vivant" » "wit:born vivant", "wit:bono vivant", "wit:bone vivant", "whit:bon vivant", "witt:bon vivant", "wait:bon vivant"
"wit:bond vivant" » "wit:bornd vivant", "wit:bonod vivant", "wit:boned vivant", "whit:bond vivant", "witt:bond vivant", "wait:bond vivant", "wit:band vivant", "wit:bono vivant", "wit:boyd 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: "((\"litt:bon vivant\") OR (((\"wit:bon vivant\") OR (\"wit:bond vivant\"))))~".
• Removing quotes may allow a broader search: (( litt:bon vivant ) OR ((( wit:bon vivant ) OR ( wit:bond vivant ))))~.
• Adding a wildcard symbol may retrieve word variants: (("litt:bon vivant") OR ((("wit:bon vivant") OR ("wit:bond vivant"))))*.
