=head1 NAME

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

=head1 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.  



=head1 DESCRIPTION

SnowballStemmer is an L<Analyzer|Lucy::Analysis::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'.
