        The force merge API allows to force merging of one or more indices
        through an API. The merge relates to the number of segments a Lucene
        index holds within each shard. The force merge operation allows to
        reduce the number of segments by merging them.

        This call will block until the merge is complete. If the http
        connection is lost, the request will continue in the background, and
        any new requests will block until the previous force merge is complete.
