+        # Remove an index block from an index.
+        # Index blocks limit the operations allowed on an index by blocking specific operation types.
+        #
+        # @option arguments [String] :index A comma-separated list or wildcard expression of index names used to limit the request.
+        #  By default, you must explicitly name the indices you are removing blocks from.
+        #  To allow the removal of blocks from indices with `_all`, `*`, or other wildcard expressions, change the `action.destructive_requires_name` setting to `false`.
+        #  You can update this setting in the `elasticsearch.yml` file or by using the cluster update settings API. (*Required*)
+        # @option arguments [String] :block The block type to remove from the index. (*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.
+        #  For example, a request targeting `foo*,bar*` returns an error if an index starts with `foo` but no index starts with `bar`. Server default: true.
+        # @option arguments [String, Array<String>] :expand_wildcards The 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.
+        #  It supports comma-separated values, such as `open,hidden`. 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 The period to wait for the master node.
+        #  If the master node is not available before the timeout expires, the request fails and returns an error.
+        #  It can also be set to `-1` to indicate that the request should never timeout. Server default: 30s.
+        # @option arguments [Time] :timeout The period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata.
+        #  If no response is received before the timeout expires, the cluster metadata update still applies but the response will indicate that it was not completely acknowledged.
+        #  It can also be set to `-1` to indicate that the request should never timeout. Server default: 30s.

+        #  readable values will be omitted. This makes sense for responses being consumed
+        #  only by machines.
