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'.
