}

以下条件需要适用：

  1. startDate $ gte ISODate（＆＃39; 2018-01-15T11：13：14.000Z＆＃39;）＆amp; endDate $ lte ISODate（＆＃39; 2018-02-12T11：13：14.000Z＆＃39;）

  2. 需要根据以下类别对其进行分组

    PremChange＆gt; 10-记录将在一组中具有限制
     APTCChange＆gt; 10-记录将在一组中有限制  MbrRespChg> 10-记录将在一组中具有限制

    3. 预期结果：

    请建议我如何编写mongodb查询，我写了一个           查询使用匹配，展开和项目，但我没有得到欲望           输出

答案 0 :(得分：0)

您可以尝试以下聚合。不确定为什么你需要在这里分组。

$match将历史数组过滤到至少一个元素在指定日期范围内的位置。

$unwind展平历史数组。

$match过滤历史文档，其中元素与指定的日期范围匹配。

$match过滤关键值大于10的历史文档。

db.col.aggregate([
  {"$match":{
  "history":{
    "$elemMatch":{
      "startDate":{"$gte":ISODate("2018-01-15T11:13:14.000Z")},
      "endDate":{"$lte":ISODate("2018-02-12T11:13:14.000Z")}
     }
   }
 }},
 {"$unwind":"$history"},
 {"$match":{
   "history.startDate":{"$gte":ISODate("2018-01-15T11:13:14.000Z")}, 
   "history.endDate":{"$lte":ISODate("2018-02-12T11:13:14.000Z")}
 }},
 {"$match":{
   "$or":[
     {"history.APTCChange":{"$gt":10}},
     {"history.PremChange":{"$gt":10}},
     {"history.MbrRespChg":{"$gt":10}}
    ]
 }}
])
