KinoSearch13pm
Search engine library
Usage
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";}

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.
