Package org.apache.lucene.codecs.blocktree Description

BlockTree terms dictionary.

This terms dictionary organizes all terms into blocks according to shared prefix, such that each block has enough terms, and then stores the prefix trie in memory as an FST as the index structure. It allows you to plug in your own PostingsWriterBase to implement the postings.

See BlockTreeTermsWriter for the file format.
