如何获取Emotions.type值为＆＃34; CONFUSED＆＃34;

的所有记录

请注意对象导航如下所示details.data.FaceRecords [0] .FaceDetail.Confidence

尝试使用聚合写几个quire但无法找到请建议一种方法来接近它

我在你的描述中看到了冲突。您已经提到要获取Emotions.type值为“CONFUSED”但后来指定了对象导航（FaceDetail.Confidence）的所有记录。

无论如何，以下查询应返回Emotions.Type为CONFUSED的所有匹配记录。

db.facialAnalysisConfiguration.find( { "details.data.FaceRecords.FaceDetail.Emotions.Type": "CONFUSED" }

mongodb查找查询不起作用
