==== Compression
*From version 0.90 onwards, all stored fields (including `_source`) are
always compressed.*
For versions before 0.90:
The source field can be compressed (LZF) when stored in the index. This
can greatly reduce the index size, as well as possibly improving
performance (when decompression overhead is better than loading a bigger
source from disk). The code takes special care to decompress the source
only when needed, for example decompressing it directly into the REST
stream of a result.
In order to enable compression, the `compress` option should be set to
`true`. By default it is set to `false`. Note, this can be changed on an
existing index, as a mix of compressed and uncompressed sources is
supported.
Moreover, a `compress_threshold` can be set to control when the source
will be compressed. It accepts a byte size value (for example `100b`,
`10kb`). Note, `compress` should be set to `true`.
