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

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.
Getter for "analyzers" member.
