NAME
       Plucene::Index::SegmentReader - the Segment reader

SYNOPSIS

DESCRIPTION
       The segment reader class.

METHODS
   new
               my $seg_reader =
                 Plucene::Index::SegmentReader->new( Plucene::Index::SegmentInfo $si);

       This will create a new Plucene::Index::SegmentReader object.

   has_deletions
               if ($seg_reader->has_deletions(Plucene::Index::SegmentInfo $si))
                       {  ... }

   files
               my @files = $seg_reader->files;

   terms
               my @terms = $seg_reader->terms;

   document
               my $doc = $seg_reader->document($id);

   is_deleted
               if ($seg_reader->is_deleted($id)) {  .. }

   term_docs
               my Plucene::Index::SegmentTermDocs $docs
                       = $seg_reader->term_docs($term);

       This will return the Plucene::Index::SegmentTermDocs object for the given term.

   term_positions
               my Plucene::Index::SegmentTermPositions $pos
                       = $seg_reader->term_positions($term);

       This will return the Plucene::Index::SegmentTermPositions object for the given term.

   doc_freq
               my $doc_freq = $seg_reader->doc_freq($term);

       This returns the number of documents containing the passed term.

   num_docs
               my $num_docs = $seg_reader->num_docs;

       This is the number of documents, excluding deleted ones.

   max_doc
               my $max_doc = $seg_reader->max_doc;

   norms
               my $norms = $seg_reader->norms($field, $offset);

       This returns the byte-encoded normalisation factor for the passed field. This is used by
       the search code to score documents.

       Note we are not using the 'offset' and 'bytes' arguments per the Java.  Instead, callers
       should use substr to put the result of "norms" into the appropriate place in a string.

   norm_stream
               my Plucene::Store::InputStream $stream
                       = $seg_reader->norm_stream($field);

       This will return the Plucene::Store::InputStream for the passed field.
