1. 查询指定时间内出现的次数

POST process-log/_search
{
    "size": 0,
    "query": {
        "bool": {
            "filter": [
                {
                    "range": {
                        "requestTime": {
                            "from": 1722470400000,
                            "to": 1722556800000
                        }
                    }
                }
            ]
        }
    },
    "aggs": {
        "server_request": {
            "terms": {
                "script": {
                    "source": "if (doc['serverName.keyword'].size() > 0 && doc['requestUri.keyword'].size() > 0) { return doc['serverName.keyword'].value + ' ' + doc['requestUri.keyword'].value; } else { return 'N/A'; }",
                    "lang": "painless"
                },
                "size": 10,
                "order": {
                    "_count": "desc"
                }
            }
        }
    }
}

2. Elasticsearch 插叙2秒内出现的次数

      }
    }
  },
  "aggs": {
    "uri_over_time": {
      "composite": {
        "size": 100, 
        "sources": [
          {
            "requestTime": {
              "date_histogram": {
                "field": "requestTime",
