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