NAME

KSx::Index::ByteBufDocWriter - Write a Doc as a fixed-width byte array.

SYNOPSIS

Create an Architecture subclass which overrides register_doc_writer() and register_doc_reader():

    package MyArchitecture;
    use base qw( KinoSearch::Plan::Architecture );
    use KSx::Index::ByteBufDocReader;
    use KSx::Index::ByteBufDocWriter;

    sub register_doc_writer {
        my ( $self, $seg_writer ) = @_; 
        my $doc_writer = KSx::Index::ByteBufDocWriter->new(
            width      => 16,
            field      => 'value',
            snapshot   => $seg_writer->get_snapshot,
            segment    => $seg_writer->get_segment,
            polyreader => $seg_writer->get_polyreader,
        );  
        $seg_writer->register(
            api       => "KinoSearch::Index::DocReader",
            component => $doc_writer,
        );  
        $seg_writer->add_writer($doc_writer);
    }

    sub register_doc_reader {
        my ( $self, $seg_reader ) = @_; 
        my $doc_reader = KSx::Index::ByteBufDocReader->new(
            width    => 16,
            field    => 'value',
            schema   => $seg_reader->get_schema,
            folder   => $seg_reader->get_folder,
            segments => $seg_reader->get_segments,
            seg_tick => $seg_reader->get_seg_tick,
            snapshot => $seg_reader->get_snapshot,
        );  
        $seg_reader->register(
            api       => 'KinoSearch::Index::DocReader',
            component => $doc_reader,
        );  
    }

    package MySchema;
    use base qw( KinoSearch::Plan::Schema );

    sub architecture { MyArchitecture->new }

Proceed as normal in your indexer app, making sure that every supplied document supplies a valid value for the field in question:

    $indexer->add_doc({
        title   => $title,
        content => $content,
        id      => $id,      # <---- Must meet spec.
    });

Then, in your search app:

    my $searcher = KinoSearch::Search::IndexSearcher->new( 
        index => '/path/to/index',
    );
    my $hits = $searcher->hits( query => $query );
    while ( my $id = $hits->next ) {
        my $real_doc = $external_document_source->fetch( $doc->{value} );
        ...
    }

DESCRIPTION

This is a proof-of-concept class to demonstrate alternate implementations for fetching documents. It is unsupported.
