/**
* A {@link StoredFieldsFormat} that is very similar to
* {@link Lucene40StoredFieldsFormat} but compresses documents in chunks in
* order to improve compression ratio.
* order to improve the compression ratio.
* <p>
* For a chunk size of <tt>chunkSize</tt> bytes, this {@link StoredFieldsFormat}
* does not support documents larger than (<tt>2<sup>31</sup> - chunkSize</tt>)
* bytes. In case this is a problem, you should use another format, such as
* {@link Lucene40StoredFieldsFormat}.
* <p>
* For optimal performance, you should use a {@link MergePolicy} that returns
* segments that have the biggest byte size first.
