Perhaps you should try some spelling variations:
"wikt:bon vivant" » "wikt:born vivant", "wikt:bond vivant", "wikt:bone vivant", "wikt:bon vivan"
"wit:con vivant" » "wit:con vivan", "whit:con vivant"
"wait:con vivant" » "wait:con vivan", "want:con vivant", "walt:con vivant", "whit:con vivant"
"wikt:korn vivant" » "wikt:korn vivan"

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 ((("wit:con vivant") OR ("wait:con vivant"))))) OR ("wikt:korn vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wikt:bon vivant\") OR (((\"wit:con vivant\") OR (\"wait:con vivant\"))))) OR (\"wikt:korn vivant\"))".
• Removing quotes may allow a broader search: (((( wikt:bon vivant ) OR ((( wit:con vivant ) OR ( wait:con vivant ))))) OR ( wikt:korn vivant )).
• Adding a wildcard symbol may retrieve word variants: (((("wikt:bon vivant") OR ((("wit:con vivant") OR ("wait:con vivant"))))) OR ("wikt:korn vivant"))*.
