/**
 * BlockTree terms dictionary.

 * <p>
 * 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 {@link
 * org.apache.lucene.codecs.PostingsWriterBase} to implement the
 * postings.

 * 
 * <p>See {@link org.apache.lucene.codecs.blocktree.BlockTreeTermsWriter}
