Bodymass Index Calculator 1.0 (Default branch)
Bodymass Index Calculator is a program that will determine your BMI (body mass index), which is your ratio of fat to other tissue. It uses your weight and height in either metric or standard systems as input. This program uses a formula by the National Heart Lung and Blood Institute and is for general knowledge. You must account for individual situations and lifestyles accordingly. Image

plucene::index::writer

Plucene::Index::Writer(3pm)				User Contributed Perl Documentation			       Plucene::Index::Writer(3pm)

NAME

       Plucene::Index::Writer - write an index.

SYNOPSIS

	       my $writer = Plucene::Index::Writer->new($path, $analyser, $create);

	       $writer->add_document($doc);
	       $writer->add_indexes(@dirs);

	       $writer->optimize; # called before close

	       my $doc_count = $writer->doc_count;

	       my $mergefactor = $writer->mergefactor;

	       $writer->set_mergefactor($value);

DESCRIPTION

       This is the writer class.

       If an index will not have more documents added for a while and optimal search performance is desired, then the "optimize" method should be
       called before the index is closed.

METHODS

   new
	       my $writer = Plucene::Index::Writer->new($path, $analyser, $create);

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

       The third argument to the constructor determines whether a new index is created, or whether an existing index is opened for the addition of
       new documents.

   mergefactor / set_mergefactor
	       my $mergefactor = $writer->mergefactor;

	       $writer->set_mergefactor($value);

       Get / set the mergefactor. It defaults to 5.

   doc_count
	       my $doc_count = $writer->doc_count;

   add_document
	       $writer->add_document($doc);

       Adds a document to the index. After the document has been added, a merge takes place if there are more than
       $Plucene::Index::Writer::mergefactor segments in the index. This defaults to 10, but can be set to whatever value is optimal for your
       application.

   optimize
	       $writer->optimize;

       Merges all segments together into a single segment, optimizing an index for search. This should be the last method called on an indexer, as
       it invalidates the writer object.

   add_indexes
	       $writer->add_indexes(@dirs);

       Merges all segments from an array of indexes into this index.

       This may be used to parallelize batch indexing.	A large document collection can be broken into sub-collections.  Each sub-collection can
       be indexed in parallel, on a different thread, process or machine.  The complete index can then be created by merging sub-collection
       indexes with this method.

       After this completes, the index is optimized.
