Lucy::Index::PolyReader - Multi-segment implementation of IndexReader.
my $polyreader = Lucy::Index::IndexReader->open( index => '/path/to/index', ); my $doc_reader = $polyreader->obtain("Lucy::Index::DocReader"); for my $doc_id ( 1 .. $polyreader->doc_max ) { my $doc = $doc_reader->fetch_doc($doc_id); print " $doc_id: $doc->{title}\n"; }
PolyReader conflates index data from multiple segments. For instance, if an index contains three segments with 10 documents each, PolyReader's doc_max() method will return 30.
Some of PolyReader's DataReader components may be less efficient or complete than the single-segment implementations accessed via SegReader.
