Examples of Lucene46Codec

org.apache.lucene.codecs.lucene46.Lucene46Codec
Implements the Lucene 4.6 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.lucene46 package documentation for file format details. @lucene.experimental @deprecated Only for reading old 4.6-4.8 segments
