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.
Merges many lexicons, termids and offsets are not kept.
This class merges the structures created by Terrier, so that we use fewer and larger inverted and direct files.
Provides classes for merging two sets of data structures, created by Terrier, into one set of data structures. The output is equivalent to the output that would have been obtained if one set of data structures had been built.
