LGTM - I suggested alternative wording too:

  • "available data nodes" might be read as "available to allocate my replicas" which isn't always true.
  • also worth mentioning total_shards_per_node.

Set to a dash delimited lower and upper bound (e.g. `0-5`) or use `all`
for the upper bound (e.g. `0-all`). Defaults to `false` (i.e. disabled).

How about

Automatically choose the number of replicas based on the number of data nodes in the cluster. Set to a dash delimited lower and upper bound (e.g. `0-5`) or use `all` for the upper bound (e.g. `0-all`). Defaults to `false` (i.e. disabled). Note that the number of replicas chosen does not take into account any other allocation rules such as <<shard-allocation-filtering,shard allocation filtering>> or `total_shards_per_node`, and this can lead to the cluster health becoming `YELLOW` if the applicable rules prevent all the replica shards from being allocated.

Thanks. I've incorporated your suggestions as well as mentioned shard allocation awareness.
