org.apache.lucene.codecs.lucene40.Lucene40RWCodec
Implements the Lucene 4.0 index format, with configurable per-field postings formats.
If you want to reuse functionality of this codec in another codec, extend {@link FilterCodec}. @see org.apache.lucene.codecs.lucene40 package documentation for file format details. @deprecated Only for reading old 4.0 segments
