Examples of Lucene49Codec

org.apache.lucene.codecs.lucene49.Lucene49Codec
Implements the Lucene 4.9 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.lucene49 package documentation for file format details. @lucene.experimental
