Examples of Lucene42Codec

org.apache.lucene.codecs.lucene42.Lucene42Codec
Implements the Lucene 4.2 index format, with configurable per-field postings and docvalues formats.
If you want to reuse functionality of this codec in another codec, extend {@link FilterCodec}. @see org.apache.lucene.codecs.lucene42 package documentation for file format details. @lucene.experimental @deprecated Only for reading old 4.2 segments
