KinoSearch1::Analysis::PolyAnalyzer - multiple analyzers in series


    my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
        language  => 'es',
    # or...
    my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
        analyzers => [


A PolyAnalyzer is a series of Analyzers -- objects which inherit from KinoSearch1::Analysis::Analyzer -- 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 an LCNormalizer, a Tokenizer, and a Stemmer will be generated for you.

Supported languages:

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



    my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
        language   => 'en',

Construct a PolyAnalyzer object. If the parameter analyzers is specified, it will override language and no attempt will be made to generate a default set of Analyzers.

  • language - Must be an ISO code from the list of supported languages.

  • analyzers - Must be an arrayref. Each element in the array must inherit from KinoSearch1::Analysis::Analyzer. 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.
