How to set segment index primary_shard number

Hi skywalking dev team:
I have a question。The skywalking store set is elasticSearch7.And our es cluster is 8 nodes.And I found that the segment index's primary_shard is 5.How to set segment index primary shard number.


我英文不好怕说不明白，我再用中文描述一下：
我们线上skywalking用的存储是es7，es集群有8个节点，然后最近因为数据量太大，我们发现每一个segment的主分片数据量都在200g左右，一共主分片有5个。我们该怎么设置，让skywalking每天创建的segment索引都可以有8个或者8个以上的分片，从而让segment主分片的数据量下降呢

Hi

indexShardsNumber x superDatasetIndexShardsFactor are the way to
control shards of trace segment and logs.
There is no way to control one specific index.
