Package org.apache.lucene.codecs.blocktree
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.
