NAME

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

SYNOPSIS

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

# or...

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

DESCRIPTION

A PolyAnalyzer is a series of Analyzers -- objects which inherit from KinoSearch::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,

METHODS

new()

Constructor. Takes two possible hash-style parameters. 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 KinoSearch::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.
