KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common words
my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'fr', ); my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new( analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ], );
A "stoplist" is collection of "stopwords": words which are common enough to be of little value when determining search results. For example, so many documents in English contain "the", "if", and "maybe" that it may improve both performance and relevance to block them. # before @token_texts = ('i', 'am', 'the', 'walrus'); # after @token_texts = ('', '', '', 'walrus');
new my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'de', ); # or... my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( stoplist => \%stoplist, ); new() takes two possible parameters, "language" and "stoplist". If "stoplist" is supplied, it will be used, overriding the behavior indicated by the value of "language". · stoplist - must be a hashref, with stopwords as the keys of the hash and values set to 1. · language - must be the ISO code for a language. Loads a default stoplist supplied by Lingua::StopWords.
