Perhaps you should try some spelling variations:
"litt:bono vivant" » "pitt:bono vivant", "lita:bono vivant", "liut:bono vivant", "litt:mono vivant", "litt:cono vivant", "litt:tono vivant", "litt:borno vivant", "litt:bondo vivant", "litt:boneo vivant"
"wantt:bon vivant" » "want:bon vivant", "wants:bon vivant", "watt:bon vivant", "wantt:born vivant", "wantt:bond vivant", "wantt:bone vivant"
"walt:hand vivant" » "wall:hand vivant", "walt:han vivant", "walt:hans vivant", "walt:had vivant"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("litt:bono vivant") OR ("wantt:bon vivant"))) OR ("walt:hand vivant"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"litt:bono vivant\") OR (\"wantt:bon vivant\"))) OR (\"walt:hand vivant\"))*".
• Removing quotes may allow a broader search: (((( litt:bono vivant ) OR ( wantt:bon vivant ))) OR ( walt:hand vivant ))*.
