NAME

       Lingua::Stem::Ru - Porter's stemming algorithm for Russian (KOI8-R only)

SYNOPSIS

	   use Lingua::Stem::Ru;
	   my $stems = Lingua::Stem::Ru::stem({ -words => $word_list_reference,
						-locale => 'ru',
						-exceptions => $exceptions_hash,
					     });

	   my $stem = Lingua::Stem::Ru::stem_word( $word );

DESCRIPTION

       This module applies the Porter Stemming Algorithm to its parameters, returning the stemmed words.

       The algorithm is implemented exactly as described in:

	   http://snowball.tartarus.org/russian/stemmer.html

       The code is carefully crafted to work in conjunction with the Lingua::Stem module by Benjamin Franz. This stemmer is also based on the work
       of Aldo Capini, see Lingua::Stem::It.

METHODS

       stem({ -words => @words, -locale => 'ru', -exceptions => \%exceptions });
	   Stems a list of passed words. Returns an anonymous list reference to the stemmed words.

	   Example:

	     my $stemmed_words = Lingua::Stem::Ru::stem({ -words => @words,
							 -locale => 'ru',
						     -exceptions => \%exceptions,
				     });

       stem_word( $word );
	   Stems a single word and returns the stem directly.

	   Example:

	     my $stem = Lingua::Stem::Ru::stem_word( $word );

       stem_caching({ -level => 0|1|2 });
	   Sets the level of stem caching.

	   '0' means 'no caching'. This is the default level.

	   '1' means 'cache per run'. This caches stemming results during a single
	       call to 'stem'.

	   '2' means 'cache indefinitely'. This caches stemming results until
	       either the process exits or the 'clear_stem_cache' method is called.

       clear_stem_cache;
	   Clears the cache of stemmed words

   EXPORT
       None by default.
