|
|
columns, it only returns the specified columns.
|
|
|
|
Valid columns are:
|
|
|
|
`index`, `i`, `idx`::
|
|
(Default) Name of the index, such as `twitter`.
|
|
|
|
`shard`, `s`, `sh`::
|
|
(Default) Name of the shard.
|
|
|
|
`prirep`, `p`, `pr`, `primaryOrReplica`::
|
|
(Default) Shard type. Returned values are `primary` or `replica`.
|
|
|
|
`ip`::
|
|
(Default) IP address of the segment's shard, such as `127.0.1.1`.
|
|
|
|
`segment`::
|
|
(Default)
|
|
include::{es-repo-dir}/rest-api/common-parms.asciidoc[tag=segment]
|
