DESCRIPTION

By default, a Lucy index consists of several main parts: lexicon, postings, stored documents, deletions, and highlight data. The readers and writers for that data are spawned by Architecture. Each component operates at the segment level; Architecture’s factory methods are used to build up SegWriter and SegReader.
