STABLE FORK

12       KinoSearch1 is a fork of KinoSearch version 0.165 intended to provide
13       stability and backwards compatibility.  For the latest features, see
14       the main branch.
15

SYNOPSIS

17       First, write an application to build an inverted index, or "invindex",
18       from your document collection.
19
20           use KinoSearch1::InvIndexer;
21           use KinoSearch1::Analysis::PolyAnalyzer;
22
23           my $analyzer
24               = KinoSearch1::Analysis::PolyAnalyzer->new( language => 'en' );
25
26           my $invindexer = KinoSearch1::InvIndexer->new(
27               invindex => '/path/to/invindex',
28               create   => 1,
29               analyzer => $analyzer,
30           );
31
32           $invindexer->spec_field(
33               name  => 'title',
34               boost => 3,
35           );
36           $invindexer->spec_field( name => 'bodytext' );
37
38           while ( my ( $title, $bodytext ) = each %source_documents ) {
39               my $doc = $invindexer->new_doc;
40
41               $doc->set_value( title    => $title );
42               $doc->set_value( bodytext => $bodytext );
43
44               $invindexer->add_doc($doc);
45           }
46
47           $invindexer->finish;
48
49       Then, write a second application to search the invindex:
50
51           use KinoSearch1::Searcher;
52           use KinoSearch1::Analysis::PolyAnalyzer;
53
54           my $analyzer
55               = KinoSearch1::Analysis::PolyAnalyzer->new( language => 'en' );
56
57           my $searcher = KinoSearch1::Searcher->new(
58               invindex => '/path/to/invindex',
59               analyzer => $analyzer,
60           );
61
62           my $hits = $searcher->search( query => "foo bar" );
63           while ( my $hit = $hits->fetch_hit_hashref ) {
64               print "$hit->{title}\n";
65           }
66

DESCRIPTION

68       KinoSearch1 is a loose port of the Java search engine library Apache
69       Lucene, written in Perl and C. The archetypal application is website
70       search, but it can be put to many different uses.
71
72   Features
73       ·   Extremely fast and scalable - can handle millions of documents
74
75       ·   Incremental indexing (addition/deletion of documents to/from an
76           existing index).
77
78       ·   Full support for 12 Indo-European languages.
79
80       ·   Support for boolean operators AND, OR, and AND NOT; parenthetical
81           groupings, and prepended +plus and -minus
82
83       ·   Algorithmic selection of relevant excerpts and highlighting of
84           search terms within excerpts
85
86       ·   Highly customizable query and indexing APIs
87
88       ·   Phrase matching
89
90       ·   Stemming
91
92       ·   Stoplists
93
94   Getting Started
95       KinoSearch1 has many, many classes, but you only need to get aquainted
96       with three to start with:
97
98       ·   KinoSearch1::InvIndexer
99
100       ·   KinoSearch1::Searcher
101
102       ·   KinoSearch1::Analysis::PolyAnalyzer
103
104       Probably the quickest way to get something up and running is to cut and
105       paste the sample applications out of KinoSearch1::Docs::Tutorial and
106       adapt them for your purposes.

History

120       Search::Kinosearch 0.02x, no longer supported, is this suite's
121       forerunner.  Plucene is a pure-Perl port of Lucene 1.3. KinoSearch is a
122       from-scratch project which attempts to draws on the lessons of both.
123       The API is not compatible with either.
124
125       KinoSearch is named for Kino, the main character in John Steinbeck's
126       novella, "The Pearl".

BUGS

133       UTF-8 scalars are not indexed properly.  This is fixed in KinoSearch
134       0.3x, but cannot be fixed in KinoSearch1 without breaking index
135       compatibility with KinoSearch 0.165 from which KinoSearch1 was forked.
136
137       Not thread-safe.
138
139       Indexing crashes reliably on Solaris 2.9 or other systems which are
140       fussy about pointer alignment.
