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

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

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