Namespace Lucene.Net.Codecs.Compressing

A codec that uses for its stored fields and delegates to for everything else.

A StoredFieldsFormat that is very similar to Lucene40StoredFieldsFormat but compresses documents in chunks in order to improve the compression ratio.

For a chunk size of chunkSize bytes, this StoredFieldsFormat does not support documents larger than (231 - chunkSize) bytes. In case this is a problem, you should use another format, such as Lucene40StoredFieldsFormat.

For optimal performance, you should use a MergePolicy that returns segments that have the biggest byte size first.

@lucene.experimental

Random-access reader for CompressingStoredFieldsIndexWriter.

@lucene.internal

Efficient index format for block-based Codecs.

this writer generates a file which can be loaded into memory using memory-efficient data structures to quickly locate the block that contains any document.

In order to have a compact in-memory representation, for every block of 1024 chunks, this index computes the average number of bytes per chunk and for every chunk, only stores the difference between

Data is written as follows:
