NAME
       KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common
       words

SYNOPSIS
	   my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
	       language => 'fr',
	   );
	   my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
	       analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ],
	   );

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
	   @token_texts = ('i', 'am', 'the', 'walrus');

	   # after
	   @token_texts = ('',	'',   '',    'walrus');

CONSTRUCTOR
   new
	   my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
	       language => 'de',
	   );

	   # or...
	   my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
	       stoplist => \%stoplist,
	   );

       new() takes two possible parameters, "language" and "stoplist".	If
       "stoplist" is supplied, it will be used, overriding the behavior
       indicated by the value of "language".

       ·   stoplist - must be a hashref, with stopwords as the keys of the
	   hash and values set to 1.

       ·   language - must be the ISO code for a language.  Loads a default
	   stoplist supplied by Lingua::StopWords.
