MongoDB聚合日期问题

我在MongoDB中有一个查询，它假定根据特定标准提取记录。我想我可能会误解聚合管道的功能。问题中的查询大部分是正确地拉动记录，但它引入了一些不符合标准的记录。它似乎是造成这个问题的查询的日期部分，我想我可能会做错了。任何帮助，将不胜感激。MongoDB聚合日期问题

查询：

var theFirst = new Date("2016", "0", "1", "0", "0", "0", "0"); 
var theLast = new Date("2017", "0", "1", "0", "0", "0", "0"); 

var query = [ 
    { $match: { $and: [{ "ProjectName": { '$regex': '^((?!win).)*$', '$options': 'i' } }, { "ProjectName": { '$regex': '^((?!Champion Cooler recommended).)*$', '$options': 'i' } }] } }, 
    { $match: { $or: [{ "Payments": { $exists: true } }, { "Reports": { $exists: true } }] } }, 
    { $match: { $or: [{ "Payments.ScheduledDate": { $lt: theLast, $gt: theFirst } }, { "Reports.ScheduledDate": { $lt: theLast, $gt: theFirst } }] } }, { 
     $lookup: { 
      from: 'winorganizations', 
      localField: 'OrganizationId', 
      foreignField: '_id', 
      as: 'orgitem' 
     } 
    }, { 
     $project: { 
      _id: 0, 
      OrgName: '$Organization', 
      Address1: '$Org_Info.Address1', 
      Address2: '$Org_Info.Address2', 
      Address3: '$Org_Info.Address3', 
      OrgCity: '$Org_Info.City', 
      OrgState: '$Org_Info.State', 
      OrgZip: '$Org_Info.Zip', 
      TaxID: '$Org_Info.TaxId', 
      orgitem: '$orgitem', 
      OrgContactName: "", 
      OrgContactEmailAddress: "", 
      GrantContactName: { "$arrayElemAt": ["$Contacts.Name", 0] }, 
      GrantContactEmail: { "$arrayElemAt": ["$Contacts.Email", 0] }, 
      GrantNbr: "$WINNbr", 
      AmtApproved: "$Amount", 
      DateAccepted: "$DateAccepted", 
      ProjectName: "$ProjectName", 
      ProgramArea: "$ProgramArea", 
      Initiative: "$Initiative", 
      Strategy: "$Strategy", 
      ProgramOfficer: "$programOfficer", 
     } 
    } 
];

这适用于大部分除了第三行{ $match: { $or: [{ "Payments.ScheduledDate": { $lt: theLast, $gt: theFirst } }, { "Reports.ScheduledDate": { $lt: theLast, $gt: theFirst } }] } },我想去的地方付款（嵌入式阵列）有greater than $gt 2016年1月1日和less than $lt 01/01指定日期的所有文件/ 2017或报告（嵌入式阵列）的预定日期为greater than $gt 01/01/2016和less than $lt 01/01/2017

它正在拉取文档，并在其中包含预定日期为12/30/2017这显然符合部分如果标准，但它喜欢它忽略$ lt。理想情况下，不应该返回此记录。

一方面，这是回报的文件有一个报告收集的是这样的：

"Reports" : [ 
    { 
     "ProgramOfficer" : "eah", 
     "ProgramOfficerId" : "eah", 
     "ApprovedDate" : ISODate("2013-12-04T06:00:00.000Z"),

     "ReportTypeId" : "30", 
     "ReportType" : "FINAL", 
     "ScheduledDate" : ISODate("2017-12-31T06:00:00.000Z"), 
     "ReportStatus" : "Pending", 
     "ReportStatusId" : ""

     "ReportStatusId" : "6eebae88-fca3-4b21-ad80-283eeb564f3f" 
    } 
]

之一的报告比2016年1月1日更大，但不低于01/01/2017.I需要查询才能拉到日期在这两个日期之间没有或两者之间的地点。

这是我希望返回的报告数组，如果我要使用$elemMatch。正如你可以看到底部有一个报告是12/31/2016这应该符合我们的标准，但它不会返回。

请添加一个重现问题的示例文档。如果至少有一个付款或报告符合条件，则问题中的$匹配解析为真。 –

我添加了一个不应该被拉的集合。问题在于$匹配功能不正常，应该是$ lt和$ gt在一起，但它只能使用看起来像$ gt的一个。 – Ohjay44

该文档是否在Payments数组中有任何内容？它是一个'或'条件，这意味着如果任何一个数组有一个匹配的项目，则它解析为真。 –

由于@Veeram，答案很简单。我需要使用$elemMatch，并且在使用时我需要将嵌入式数组视为查询中的迭代对象。

最后的工作代码：

var query = [ 
{ $match: { $and: [{ "ProjectName": { '$regex': '^((?!win).)*$', '$options': 'i' } }, { "ProjectName": { '$regex': '^((?!Champion Cooler recommended).)*$', '$options': 'i' } }] } }, 
{ $match: { $or: [{ "Payments": { $exists: true } }, { "Reports": { $exists: true } }] } }, 
{ $match: { $or: [{ "Payments": {$elemMatch: {"ScheduledDate": { $lt: theLast, $gte: theFirst } } } }, { "Reports": {$elemMatch: {"ScheduledDate": { $lt: theLast, $gte: theFirst } } } }] } }, { 
    $lookup: { 
     from: 'winorganizations', 
     localField: 'OrganizationId', 
     foreignField: '_id', 
     as: 'orgitem' 
    } 
}, { 
    $project: { 
     _id: 0, 
     OrgName: '$Organization', 
     Address1: '$Org_Info.Address1', 
     Address2: '$Org_Info.Address2', 
     Address3: '$Org_Info.Address3', 
     OrgCity: '$Org_Info.City', 
     OrgState: '$Org_Info.State', 
     OrgZip: '$Org_Info.Zip', 
     TaxID: '$Org_Info.TaxId', 
     orgitem: '$orgitem', 
     OrgContactName: "", 
     OrgContactEmailAddress: "", 
     GrantContactName: { "$arrayElemAt": ["$Contacts.Name", 0] }, 
     GrantContactEmail: { "$arrayElemAt": ["$Contacts.Email", 0] }, 
     GrantNbr: "$WINNbr", 
     AmtApproved: "$Amount", 
     DateAccepted: "$DateAccepted", 
     ProjectName: "$ProjectName", 
     ProgramArea: "$ProgramArea", 
     Initiative: "$Initiative", 
     Strategy: "$Strategy", 
     ProgramOfficer: "$programOfficer", 
    } 
} 
];

在第三行，我用$elemMatch和工作你会看到。
