NAME

Lucy::Index::SegReader - Single-segment IndexReader.

SYNOPSIS

    my $polyreader = Lucy::Index::IndexReader->open(
        index => '/path/to/index',
    );
    my $seg_readers = $polyreader->seg_readers;
    for my $seg_reader (@$seg_readers) {
        my $seg_name = $seg_reader->get_seg_name;
        my $num_docs = $seg_reader->doc_max;
        print "Segment $seg_name ($num_docs documents):\n";
        my $doc_reader = $seg_reader->obtain("Lucy::Index::DocReader");
        for my $doc_id ( 1 .. $num_docs ) {
            my $doc = $doc_reader->fetch_doc($doc_id);
            print "  $doc_id: $doc->{title}\n";
        }
    }

DESCRIPTION

SegReader interprets the data within a single segment of an index.

Generally speaking, only advanced users writing subclasses which manipulate data at the segment level need to deal with the SegReader API directly.

Nearly all of SegReader's functionality is implemented by pluggable components spawned by Architecture's factory methods.

METHODS

get_seg_name()

Return the name of the segment.

get_seg_num()

Return the number of the segment.
