solr - SOLR 查询返回值，但 stats.countDistinct 仍然缺失

Question

这是我的 solr 查询，结果返回了一些值，但无法计算 distinct ：

"stats.field":"deviceId"
"numFound":38
"deviceId":"11004084101MTVCN240D63C00010"
"missing":38
"distinctValues":[]

这是完整的回复：

{
  "responseHeader": {
    "status": 0,
    "QTime": 0,
    "params": {
      "q": "*:*",
      "stats.calcdistinct": "true",
      "indent": "on",

        "tenant:mailink.MKH13.KVMB.DXHN1"
      ],
      "rows": "1",
      "wt": "json",
      "stats.field": "deviceId"
    }
  },
  "response": {

      }
    ]
  },
  "stats": {
    "stats_fields": {
      "deviceId": {
        "min": null,
        "max": null,
        "count": 0,

        "distinctValues": [],
        "countDistinct": 0
      }
    }
  }
}
