elasticsearch - 弹性检索中的嵌套JSON没有被提取

Question

我具有以下JSON结构:

{
    "Dataset": "kh_offers",
    "Instance": "20140817",
    "Record": [{
        "45": "{\"errorCode\":null,\"runStatusId\":null,\"lakeHdfsPath\":\"/user/jmblnvr/20140817_011500_zoot_kohls_offer_init.dat\",\"fieldIndex\":45,\"datasetFieldName\":\"PRESENTABLE_FLAG\",\"datasetFieldSum\":0.0,\"datasetFieldMin\":0.0,\"datasetFieldMax\":0.0,\"datasetFieldMean\":0.0,\"datasetFieldSigma\":0.0,\"datasetFieldNullCount\":0.0,\"datasetFieldObsCount\":0.0,\"datasetFieldKurtosis\":0.0,\"datasetFieldSkewness\":0.0,\"frequencyDistribution\":\"(T,170544)\",\"id\":null,\"fieldType\":\"STRING\"}"
    }, {
        "30": "{\"errorCode\":null,\"runStatusId\":null,\"lakeHdfsPath\":\"/user/jmblnvr/20140817_011500_zoot_kohls_offer_init.dat\",\"fieldIndex\":30,\"datasetFieldName\":\"FIRST_PYMT_DATE\",\"datasetFieldSum\":0.0,\"datasetFieldMin\":0.0,\"datasetFieldMax\":0.0,\"datasetFieldMean\":0.0,\"datasetFieldSigma\":0.0,\"datasetFieldNullCount\":0.0,\"datasetFieldObsCount\":0.0,\"datasetFieldKurtosis\":0.0,\"datasetFieldSkewness\":0.0,\"frequencyDistribution\":null,\"id\":null,\"fieldType\":\"STRING\"}"
    }]
}

我想知道为什么 flex 搜索无法处理此嵌套结构？是因为我的作家在编写它时使用奇怪的\使其成为有效的JSON吗？还有其他原因吗？

Elastic Search正在获取前三个字段，但是当我深入记录时，它只是在考虑它的一个整体字符串。

您将其作为字符串传递，因为您已将其用引号引起来并且将“内部”引号转义。只需传入JSON:

{
    "Dataset": "kh_offers",
    "Instance": "20140817",
    "Record": [{
        "45": {
            "errorCode": null,
            "runStatusId": null,
            "lakeHdfsPath": "/user/jmblnvr/20140817_011500_zoot_kohls_offer_init.dat",
            "fieldIndex": 45,
            "datasetFieldName": "PRESENTABLE_FLAG",
            "datasetFieldSum": 0.0,
            "datasetFieldMin": 0.0,
            "datasetFieldMax": 0.0,
            "datasetFieldMean": 0.0,
            "datasetFieldSigma": 0.0,
            "datasetFieldNullCount": 0.0,
            "datasetFieldObsCount": 0.0,
            "datasetFieldKurtosis": 0.0,
            "datasetFieldSkewness": 0.0,
            "frequencyDistribution": "(T,170544)",
            "id": null,
            "fieldType": "STRING"
        }
    }, {

            "lakeHdfsPath": "/user/jmblnvr/20140817_011500_zoot_kohls_offer_init.dat",
            "fieldIndex": 30,
            "datasetFieldName": "FIRST_PYMT_DATE",
            "datasetFieldSum": 0.0,
            "datasetFieldMin": 0.0,
            "datasetFieldMax": 0.0,

            "datasetFieldObsCount": 0.0,
            "datasetFieldKurtosis": 0.0,
            "datasetFieldSkewness": 0.0,
            "frequencyDistribution": null,
            "id": null,
            "fieldType": "STRING"
        }
    }]
}
