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. perl v5.12.4 2011-08-14 Plucene::Index::Writer(3pm)
