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'.
