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

Reduce related words to a shared root.

## NAME

Lucy::Analysis::SnowballStemmer - Reduce related words to a shared root.

## SYNOPSIS

```
    my $stemmer = Lucy::Analysis::SnowballStemmer->new( language => 'es' );

    my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
        analyzers => [ $case_folder, $tokenizer, $stemmer ],
    );
```

This class is a wrapper around the Snowball stemming library, so it supports the same languages.

## DESCRIPTION

SnowballStemmer is an Analyzer which reduces related words to a root form (using the "Snowball" stemming library).  For instance, "horse", "horses", and "horsing" all become "hors" -- so that a search for 'horse' will also match documents containing 'horses' and 'horsing'.

## CONSTRUCTORS

### new( *\[labeled params\]* )

```
    my $stemmer = Lucy::Analysis::SnowballStemmer->new( language => 'es' );
```
