[Type] string [Description] Configure the way query words are removed when the query doesn't retrieve any results. This option can be used to avoid having an empty result page. There is three different options: lastWords: when a query does not return any result, the last word will be added as optionalWords (the process is repeated with the n-1 word, n-2 word, ... until there is results). This option is particularly useful on e-commerce websites firstWords: when a query does not return any result, the first word will be added as optionalWords (the process is repeated with the second word, third word, ... until there is results). This option is useful on address search allOptional: When a query does not return any result, a second trial will be made with all words as optional (which is equivalent to transforming the AND operand between query terms in a OR operand) none: No specific processing is done when a query does not return any result. (Default to None) [Name]
