7       array.

SYNOPSIS

10       Create an Architecture subclass which overrides register_doc_writer()
11       and register_doc_reader():
12
13           package MyArchitecture;
14           use base qw( Lucy::Plan::Architecture );
15           use LucyX::Index::ByteBufDocReader;
16           use LucyX::Index::ByteBufDocWriter;
17
18           sub register_doc_writer {
19               my ( $self, $seg_writer ) = @_;
20               my $doc_writer = LucyX::Index::ByteBufDocWriter->new(
21                   width      => 16,
22                   field      => 'value',
23                   snapshot   => $seg_writer->get_snapshot,
24                   segment    => $seg_writer->get_segment,
25                   polyreader => $seg_writer->get_polyreader,
26               );
27               $seg_writer->register(
28                   api       => "Lucy::Index::DocReader",
29                   component => $doc_writer,
30               );
31               $seg_writer->add_writer($doc_writer);
32           }
33
34           sub register_doc_reader {
35               my ( $self, $seg_reader ) = @_;
36               my $doc_reader = LucyX::Index::ByteBufDocReader->new(
37                   width    => 16,
38                   field    => 'value',
39                   schema   => $seg_reader->get_schema,
40                   folder   => $seg_reader->get_folder,
41                   segments => $seg_reader->get_segments,
42                   seg_tick => $seg_reader->get_seg_tick,
43                   snapshot => $seg_reader->get_snapshot,
44               );
45               $seg_reader->register(
46                   api       => 'Lucy::Index::DocReader',
47                   component => $doc_reader,
48               );
49           }
50
51           package MySchema;
52           use base qw( Lucy::Plan::Schema );
53
54           sub architecture { MyArchitecture->new }
55
56       Proceed as normal in your indexer app, making sure that every supplied
57       document supplies a valid value for the field in question:
58
59           $indexer->add_doc({
60               title   => $title,
61               content => $content,
62               id      => $id,      # <---- Must meet spec.
63           });
64
65       Then, in your search app:
66
67           my $searcher = Lucy::Search::IndexSearcher->new(
68               index => '/path/to/index',
69           );
70           my $hits = $searcher->hits( query => $query );
71           while ( my $id = $hits->next ) {
72               my $real_doc = $external_document_source->fetch( $doc->{value} );
73               ...
74           }
75

DESCRIPTION

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