KinoSearch1::Analysis:UserpContributed PerKinoSearch1::Analysis::Stopalizer(3)NAMEKinoSearch1::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.
