# Lucy::Analysis::PolyAnalyzer(3pm)

Multiple Analyzers in series.

## 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.
