Lucy::Index::SegWriter - Write one segment of an index.
SegWriter is a conduit through which information fed to Indexer passes. It manages Segment and Inverter, invokes the Analyzer chain, and feeds low level DataWriters such as PostingListWriter and DocWriter.
The sub-components of a SegWriter are determined by Architecture. DataWriter components which are added to the stack of writers via add_writer() have Add_Inverted_Doc() invoked for each document supplied to SegWriter’s add_doc().
$seg_writer->register( api => $api # required component => $component # required );
my $obj = $seg_writer->fetch($api);
Retrieve a registered component.
Add a DataWriter to the SegWriter’s stack of writers.
$seg_writer->add_doc( doc => $doc # required boost => $boost # default: 1.0 );
Add a document to the segment. Inverts
doc, increments the Segment’s internal document id, then calls Add_Inverted_Doc(), feeding all sub-writers.
$seg_writer->add_segment( reader => $reader # required doc_map => $doc_map # default: undef );
Add content from an existing segment into the one currently being written.
Complete the segment: close all streams, store metadata, etc.
