NAME
       KinoSearch::Analysis::Stopalizer - Suppress a "stoplist" of common
       words.

SYNOPSIS
	   my $stopalizer = KinoSearch::Analysis::Stopalizer->new(
	       language => 'fr',
	   );
	   my $polyanalyzer = KinoSearch::Analysis::PolyAnalyzer->new(
	       analyzers => [ $case_folder, $tokenizer, $stopalizer, $stemmer ],
	   );

       This class uses Lingua::StopWords for its default stoplists, so it
       supports the same set of languages.

DESCRIPTION
       A "stoplist" is collection of "stopwords": words which are common
       enough to be of little value when determining search results.  For
       example, so many documents in English contain "the", "if", and "maybe"
       that it may improve both performance and relevance to block them.

       Before filtering stopwords:

	   ( "i", "am", "the", "walrus" )

       After filtering stopwords:

	   ( "walrus" )

       Stopalizer provides default stoplists for several languages, courtesy
       of the Snowball project (<http://snowball.tartarus.org>), or you may
       supply your own.
