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