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