NAME

6       KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common
7       words
8

SYNOPSIS

10           my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
11               language => 'fr',
12           );
13           my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new(
14               analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ],
15           );
16

DESCRIPTION

18       A "stoplist" is collection of "stopwords": words which are common
19       enough to be of little value when determining search results.  For
20       example, so many documents in English contain "the", "if", and "maybe"
21       that it may improve both performance and relevance to block them.
22
23           # before
24           @token_texts = ('i', 'am', 'the', 'walrus');
25
26           # after
27           @token_texts = ('',  '',   '',    'walrus');

CONSTRUCTOR

30   new
31           my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
32               language => 'de',
33           );
34
35           # or...
36           my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
37               stoplist => \%stoplist,
38           );
39
40       new() takes two possible parameters, "language" and "stoplist".  If
41       "stoplist" is supplied, it will be used, overriding the behavior
42       indicated by the value of "language".
43
44       ·   stoplist - must be a hashref, with stopwords as the keys of the
45           hash and values set to 1.
46
47       ·   language - must be the ISO code for a language.  Loads a default
48           stoplist supplied by Lingua::StopWords.
