NAME

KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common words

CONTENTS

SYNOPSIS



    my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
        language => fr,
    );
    my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
        analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ],
    );



DESCRIPTION

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);



CONSTRUCTOR

    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.
o <B>stoplistB> - must be a hashref, with stopwords as the keys of the hash and values set to 1.
o <B>languageB> - must be the ISO code for a language. Loads a default stoplist supplied by Lingua::StopWords.
