NAME
KinoSearch1 - search engine library
VERSION
1.01
STABLE FORK
KinoSearch1 is a fork of KinoSearch version 0.165 intended to provide stability and backwards
compatibility. For the latest features, see the main branch.
SYNOPSIS
First, write an application to build an inverted index, or "invindex", from your document collection.
use KinoSearch1::InvIndexer;
use KinoSearch1::Analysis::PolyAnalyzer;
my $analyzer
= KinoSearch1::Analysis::PolyAnalyzer->new( language => 'en' );
my $invindexer = KinoSearch1::InvIndexer->new(
invindex => '/path/to/invindex',
create => 1,
analyzer => $analyzer,
);
$invindexer->spec_field(
name => 'title',
boost => 3,
);
$invindexer->spec_field( name => 'bodytext' );
while ( my ( $title, $bodytext ) = each %source_documents ) {
my $doc = $invindexer->new_doc;
$doc->set_value( title => $title );
$doc->set_value( bodytext => $bodytext );
$invindexer->add_doc($doc);
}
$invindexer->finish;
Then, write a second application to search the invindex:
use KinoSearch1::Searcher;
use KinoSearch1::Analysis::PolyAnalyzer;
my $analyzer
= KinoSearch1::Analysis::PolyAnalyzer->new( language => 'en' );
my $searcher = KinoSearch1::Searcher->new(
invindex => '/path/to/invindex',
analyzer => $analyzer,
);
my $hits = $searcher->search( query => "foo bar" );
while ( my $hit = $hits->fetch_hit_hashref ) {
print "$hit->{title}\n";
}
DESCRIPTION
KinoSearch1 is a loose port of the Java search engine library Apache Lucene, written in Perl and C. The
archetypal application is website search, but it can be put to many different uses.
Features
• Extremely fast and scalable - can handle millions of documents
• Incremental indexing (addition/deletion of documents to/from an existing index).
• Full support for 12 Indo-European languages.
• Support for boolean operators AND, OR, and AND NOT; parenthetical groupings, and prepended +plus and
-minus
• Algorithmic selection of relevant excerpts and highlighting of search terms within excerpts
• Highly customizable query and indexing APIs
• Phrase matching
• Stemming
• Stoplists
Getting Started
KinoSearch1 has many, many classes, but you only need to get acquainted with three to start with:
• KinoSearch1::InvIndexer
• KinoSearch1::Searcher
• KinoSearch1::Analysis::PolyAnalyzer
Probably the quickest way to get something up and running is to cut and paste the sample applications out
of KinoSearch1::Docs::Tutorial and adapt them for your purposes.

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

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