        # @option arguments [String] :index The name of the index to unfreeze
        # @option arguments [Time] :timeout Explicit operation timeout
        # @option arguments [Time] :master_timeout Specify timeout for connection to master
        # @option arguments [Boolean] :ignore_unavailable Whether specified concrete indices should be ignored when unavailable (missing or closed)
        # @option arguments [Boolean] :allow_no_indices Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes `_all` string or when no indices have been specified)
        # @option arguments [String] :expand_wildcards Whether to expand wildcard expression to concrete indices that are open, closed or both. (options: open, closed, hidden, none, all)
        # @option arguments [String] :wait_for_active_shards Sets the number of active shards to wait for before the operation returns.
        # @option arguments [Hash] :headers Custom HTTP headers

        # Frozen indices are deprecated because they provide no benefit given improvements in heap memory utilization. They will be removed in a future release.
