NAME

KinoSearch::Analysis::PolyAnalyzer - Multiple Analyzers in series.

SYNOPSIS

    my $schema = KinoSearch::Plan::Schema->new;
    my $polyanalyzer = KinoSearch::Analysis::PolyAnalyzer->new( 
        language => 'en',
    );
    my $type = KinoSearch::Plan::FullTextType->new(
        analyzer => $polyanalyzer,
    );
    $schema->spec_field( name => 'title',   type => $type );
    $schema->spec_field( name => 'content', type => $type );

DESCRIPTION

A PolyAnalyzer is a series of Analyzers, each of which will be called upon to "analyze" text in turn. You can either provide the Analyzers yourself, or you can specify a supported language, in which case a PolyAnalyzer consisting of a CaseFolder, a Tokenizer, and a Stemmer will be generated for you.

Supported languages:

    en => English,
    da => Danish,
    de => German,
    es => Spanish,
    fi => Finnish,
    fr => French,
    hu => Hungarian,
    it => Italian,
    nl => Dutch,
    no => Norwegian,
    pt => Portuguese,
    ro => Romanian,
    ru => Russian,
    sv => Swedish,
    tr => Turkish,

CONSTRUCTORS

new( [labeled params] )

    my $analyzer = KinoSearch::Analysis::PolyAnalyzer->new(
        language  => 'es',
    );
    
    # or...

    my $case_folder  = KinoSearch::Analysis::CaseFolder->new;
    my $tokenizer    = KinoSearch::Analysis::Tokenizer->new;
    my $stemmer      = KinoSearch::Analysis::Stemmer->new( language => 'en' );
    my $polyanalyzer = KinoSearch::Analysis::PolyAnalyzer->new(
        analyzers => [ $case_folder, $whitespace_tokenizer, $stemmer, ], );

• language - An ISO code from the list of supported languages.

• analyzers - An array of Analyzers. The order of the analyzers matters. Don't put a Stemmer before a Tokenizer (can't stem whole documents or paragraphs -- just individual words), or a Stopalizer after a Stemmer (stemmed words, e.g. "themselv", will not appear in a stoplist). In general, the sequence should be: normalize, tokenize, stopalize, stem.

METHODS

get_analyzers()

Getter for "analyzers" member.
