Class Summary

Class	Description
BlockStructureMerger	This class merges two sets of data structures (ie direct index, inverted index, document index, lexicon and statistics), created by Terrier with position information (blocks) and possibly field information, into one set of data structures.
LexiconMerger	Merges many lexicons, termids and offsets are not kept.
StructureMerger	This class merges the structures created by Terrier, so that we use fewer and larger inverted and direct files.
