Perhaps you should try some spelling variations:
"wilt:bon vivant" » "walt:bon vivant", "wild:bon vivant", "wilf:bon vivant", "wilt:born vivant", "wilt:bond vivant", "wilt:bone vivant"
"wit:bono vivant" » "wit:borno vivant", "wit:bondo vivant", "wit:boneo vivant", "whit:bono vivant", "witt:bono vivant", "wit:mono vivant", "wit:cono vivant", "wit:tono vivant"
"wait:bono vivant" » "wait:borno vivant", "wait:bondo vivant", "wait:boneo vivant", "wait:mono vivant", "wait:cono vivant", "wait:tono vivant", "waite:bono vivant", "walt:bono vivant", "want:bono vivant"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("wilt:bon vivant") OR ((("wit:bono vivant") OR ("wait:bono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wilt:bon vivant\") OR (((\"wit:bono vivant\") OR (\"wait:bono vivant\"))))".
• Removing quotes may allow a broader search: (( wilt:bon vivant ) OR ((( wit:bono vivant ) OR ( wait:bono vivant )))).
• Adding a wildcard symbol may retrieve word variants: (("wilt:bon vivant") OR ((("wit:bono vivant") OR ("wait:bono vivant"))))*.
