A query was performed that didn't originate from our team, and this caused a brief breakdown. Do you know where this query originates from?  
The version is 6.8 and I am using elasticsearch, not opensearch.

```auto
{
    "size": 0,
    "query": {
        "terms": {
            "_index": [
                "index1",
                "index2",
                "index3",
                ......,
                "indexN",
            ],
            "boost": 1
        }
    },
    "aggregations": {
        "indices": {
            "terms": {
                "field": "_index",
                "size": 200,
                "min_doc_count": 1,
                "shard_min_doc_count": 0,
                "show_term_doc_count_error": false,
                "order": [
                    {
                        "_count": "desc"
                    },
                    {
                        "_key": "asc"
                    }
                ]
            }
        }
    }
}

```

May be a monitoring tool?

But you should upgrade to 7.17.12.
