        # Close an index.
        # A closed index is blocked for read or write operations and does not allow all operations that opened indices allow.
        # It is not possible to index documents or to search for documents in a closed index.
        # Closed indices do not have to maintain internal data structures for indexing or searching documents, which results in a smaller overhead on the cluster.
        # When opening or closing an index, the master node is responsible for restarting the index shards to reflect the new state of the index.
        # The shards will then go through the normal recovery process.
        # The data of opened and closed indices is automatically replicated by the cluster to ensure that enough shard copies are safely kept around at all times.
        # You can open and close multiple indices.
        # An error is thrown if the request explicitly refers to a missing index.
        # This behaviour can be turned off using the `ignore_unavailable=true` parameter.
        # By default, you must explicitly name the indices you are opening or closing.
        # To open or close indices with `_all`, `*`, or other wildcard expressions, change the`action.destructive_requires_name` setting to `false`. This setting can also be changed with the cluster update settings API.
        # Closed indices consume a significant amount of disk-space which can cause problems in managed environments.
        # Closing indices can be turned off with the cluster settings API by setting `cluster.indices.close.enable` to `false`.
        #
        # @option arguments [String, Array] :index Comma-separated list or wildcard expression of index names used to limit the request. (*Required*)
        # @option arguments [Boolean] :allow_no_indices If `false`, the request returns an error if any wildcard expression, index alias, or `_all` value targets only missing or closed indices.
        #  This behavior applies even if the request targets other open indices. Server default: true.
        # @option arguments [String, Array<String>] :expand_wildcards Type of index that wildcard patterns can match.
        #  If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
        #  Supports comma-separated values, such as `open,hidden`.
        #  Valid values are: `all`, `open`, `closed`, `hidden`, `none`. Server default: open.
        # @option arguments [Boolean] :ignore_unavailable If `false`, the request returns an error if it targets a missing or closed index.
        # @option arguments [Time] :master_timeout Period to wait for a connection to the master node.
        #  If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.
        # @option arguments [Time] :timeout Period to wait for a response.
        #  If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.
        # @option arguments [Integer, String] :wait_for_active_shards The number of shard copies that must be active before proceeding with the operation.
        #  Set to `all` or any positive integer up to the total number of shards in the index (`number_of_replicas+1`). Server default: 1.
        # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
        #  when they occur.
        # @option arguments [String] :filter_path Comma-separated list of filters in dot notation which reduce the response
        #  returned by Elasticsearch.
        # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
        #  For example `"exists_time": "1h"` for humans and
        #  `"eixsts_time_in_millis": 3600000` for computers. When disabled the human
        #  readable values will be omitted. This makes sense for responses being consumed
        #  only by machines.
        # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
        #  this option for debugging only.
        # @option arguments [Hash] :headers Custom HTTP headers
        #
