• Performing a fuzzy search may retrieve terms with similar spellings: (((("wikt:bon vivant") OR ("wit:con vivant"))) OR ((("wikt:korn vivant") OR ("witt:korn vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"wikt:bon vivant\") OR (\"wit:con vivant\"))) OR (((\"wikt:korn vivant\") OR (\"witt:korn vivant\"))))".
• Removing quotes may allow a broader search: (((( wikt:bon vivant ) OR ( wit:con vivant ))) OR ((( wikt:korn vivant ) OR ( witt:korn vivant )))).
• Adding a wildcard symbol may retrieve word variants: (((("wikt:bon vivant") OR ("wit:con vivant"))) OR ((("wikt:korn vivant") OR ("witt:korn vivant"))))*.
