Lucy::Analysis::SnowballStemmer(3) 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'.
