• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wilf:bon vivant\") OR (\"wild:bon vivant\"))) OR (((\"wit:tono vivant\") OR (\"witt:born vivant\"))))".
• Removing quotes may allow a broader search: (((( wilf:bon vivant ) OR ( wild:bon vivant ))) OR ((( wit:tono vivant ) OR ( witt:born vivant )))).
• Adding a wildcard symbol may retrieve word variants: (((("wilf:bon vivant") OR ("wild:bon vivant"))) OR ((("wit:tono vivant") OR ("witt:born vivant"))))*.
