SYNOPSIS

9           my $schema = Lucy::Plan::Schema->new;
10           my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
11               analyzers => \@analyzers,
12           );
13           my $type = Lucy::Plan::FullTextType->new(
14               analyzer => $polyanalyzer,
15           );
16           $schema->spec_field( name => 'title',   type => $type );
17           $schema->spec_field( name => 'content', type => $type );

DESCRIPTION

20       A PolyAnalyzer is a series of Analyzers, each of which will be called
21       upon to XanalyzeX text in turn.  You can either provide the Analyzers
22       yourself, or you can specify a supported language, in which case a
23       PolyAnalyzer consisting of a CaseFolder, a RegexTokenizer, and a
24       SnowballStemmer will be generated for you.
25
26       The language parameter is DEPRECATED. Use EasyAnalyzer instead.
27
28       Supported languages:
29
30           en => English,
31           da => Danish,
32           de => German,
33           es => Spanish,
34           fi => Finnish,
35           fr => French,
36           hu => Hungarian,
37           it => Italian,
38           nl => Dutch,
39           no => Norwegian,
40           pt => Portuguese,
41           ro => Romanian,
42           ru => Russian,
43           sv => Swedish,
44           tr => Turkish,

CONSTRUCTORS

47   new
48           my $tokenizer    = Lucy::Analysis::StandardTokenizer->new;
49           my $normalizer   = Lucy::Analysis::Normalizer->new;
50           my $stemmer      = Lucy::Analysis::SnowballStemmer->new( language => 'en' );
51           my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
52               analyzers => [ $tokenizer, $normalizer, $stemmer, ], );
53
54       Create a new PolyAnalyzer.
55
56       ·   language - An ISO code from the list of supported languages.
57           DEPRECATED, use EasyAnalyzer instead.
58
59       ·   analyzers - An array of Analyzers.  The order of the analyzers
60           matters.  DonXt put a SnowballStemmer before a RegexTokenizer
61           (canXt stem whole documents or paragraphs X just individual words),
62           or a SnowballStopFilter after a SnowballStemmer (stemmed words,
63           e.g. XthemselvX, will not appear in a stoplist).  In general, the
64           sequence should be: tokenize, normalize, stopalize, stem.
65

METHODS

67   get_analyzers
68           my $arrayref = $poly_analyzer->get_analyzers();
69
70       Getter for XanalyzersX member.
71
72   transform
73           my $inversion = $poly_analyzer->transform($inversion);
74
75       Take a single Inversion as input and returns an Inversion, either the
76       same one (presumably transformed in some way), or a new one.
77
78       ·   inversion - An inversion.
