NAME

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

SYNOPSIS

my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
    language  => 'es',
);

# or...
my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
    analyzers => [
        $lc_normalizer,
        $custom_tokenizer,
        $snowball_stemmer,
    ],
);

DESCRIPTION

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,

CONSTRUCTOR

new()

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.
