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