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.

       Supported languages:

           en => English,
           da => Danish,
           de => German,
           es => Spanish,
           fi => Finnish,
           fr => French,
           hu => Hungarian,
           it => Italian,
           nl => Dutch,
           no => Norwegian,
           pt => Portuguese,
           ro => Romanian,
           ru => Russian,
           sv => Swedish,
           tr => Turkish,

CONSTRUCTORS

   new( [labeled params] )
           my $analyzer = Lucy::Analysis::PolyAnalyzer->new(
               language  => 'es',
           );

           # or...

           my $case_folder  = Lucy::Analysis::CaseFolder->new;
           my $tokenizer    = Lucy::Analysis::RegexTokenizer->new;
           my $stemmer      = Lucy::Analysis::SnowballStemmer->new( language => 'en' );
           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.

METHODS

   get_analyzers()
       Getter for "analyzers" member.
