KinoSearch::Analysis::PolyAnalyzer - Multiple analyzers in series.
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, ], );
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,
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.
analyzers
language
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.
