Lucy::Analysis::PolyAnalyzer - Multiple Analyzers in series.
my $schema = Lucy::Plan::Schema->new; my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new( analyzers => \@analyzers, ); my $type = Lucy::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 RegexTokenizer, and a SnowballStemmer will be generated for you.
The language parameter is DEPRECATED. Use EasyAnalyzer instead.

Create a new PolyAnalyzer.
language - An ISO code from the list of supported languages. DEPRECATED, use EasyAnalyzer instead.
analyzers - An array of Analyzers. The order of the analyzers matters. Don’t put a SnowballStemmer before a RegexTokenizer (can’t stem whole documents or paragraphs – just individual words), or a SnowballStopFilter after a SnowballStemmer (stemmed words, e.g. “themselv”, will not appear in a stoplist). In general, the sequence should be: tokenize, normalize, stopalize, stem.
my $arrayref = $poly_analyzer->get_analyzers();
Getter for “analyzers” member.
my $inversion = $poly_analyzer->transform($inversion);
Take a single Inversion as input and returns an Inversion, either the same one (presumably transformed in some way), or a new one.
inversion - An inversion.
