NAME
Lucy::Analysis::PolyAnalyzer - Multiple Analyzers in series.
SYNOPSIS
my $schema = Lucy::Plan::Schema->new;
my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
language => 'en',
);
my $type = Lucy::Plan::FullTextType->new(
analyzer => $polyanalyzer,
);
$schema->spec_field( name => 'title', type => $type );
$schema->spec_field( name => 'content', type => $type );DESCRIPTION
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.

my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
analyzers => [ $case_folder, $whitespace_tokenizer, $stemmer, ], );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 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: normalize, tokenize, stopalize, stem.
