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.
