db.collection.aggregate([
  {
    $match: {
      "Att Date": {
        $gte: "2019-09-01",
        $lte: "2019-09-30"
      }
    }
  }
])

预期输出

所有文档都应提取。

Answer 1

您要比较"2019-09-01",的字符串和ISODate("2019-09-11T18:30:00Z")的日期

尝试比较日期和日期

db.collection.aggregate([
  {
    $match: {
      "Att Date": {
        $gte: ISODate("2019-09-01"),
        $lte: ISODate("2019-09-30")
      }
    }
  }
])

为什么过滤时找不到文档？
