Mongodb子文档日期范围返回错误的结果

Question

第一次在堆栈溢出。我试图在数组集合上运行日期范围查询，但是Mongo返回的无关文档不符合我的标准。我通过PHP驱动程序、Doctrine查询生成器或Mongodb进行查询并不重要。

以下是我的疑问：

db.deals.find( { "total_sold.created_at": 
                    { $gt: new ISODate("2014-03-05T00:00:00Z"),
                      $lt: new ISODate("2014-03-05T23:59:00Z") 
                    }
               }).limit(1).pretty()

其结果是：

    {
    "_id" : "1241412fb99a11a0bc70032a2cb6059b",

    "total_sold" : [
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-13T15:48:35Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-14T10:26:19Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-15T11:36:50Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-17T09:35:19Z"), 
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-19T16:34:52Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-21T12:06:10Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-02-24T09:52:23Z"),
        },
        {
            "some_field": "value",
            "created_at" : ISODate("2014-03-07T22:40:37Z"),
        }
    ],
    "updated_at" : ISODate("2014-03-07T22:40:40Z")
}    

我试图使用"total_sold.created_at“字段查询文档，将其设置为"2014-03-05"，但返回的结果不包括在"2014-03-05”中创建的任何子集合，我遗漏了什么？我尝试过$and运算符、"$total_sold.created_at“表示法等等，但没有结果。

Ps: total_sold.created_at字段是索引的。

编辑:我通过Doctrine创建并持久化我的文档。这是我的Doctrine-Mongodb映射。用于主文档和total_sold子文档.

<?php

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;
use Gedmo\Mapping\Annotation as Gedmo;


/**
 * @ODM\Document(
 *   collection="deals",
 * )
 * @ODM\Index(keys={"total_sold"="desc"}),
 */
Class Deal {

    /**
     * @ODM\Id(strategy="NONE")
     */
    protected $id;

    /**
    *Some other fields
    **/


    /**
     * @ODM\EmbedMany(targetDocument="DealTotalSold")
     */
    protected $total_sold;


    /**
     * Constructor
     */
    public function __construct() {
        $this->total_sold = new \Doctrine\Common\Collections\ArrayCollection();
    }



    /**
     * Add totalSold
     *
     */
    public function addTotalSold($totalSold) {
        $this->total_sold[] = $totalSold;
    }

    /**
     * Remove totalSold
     *
     */
    public function removeTotalSold($totalSold) {
        $this->total_sold->removeElement($totalSold);
    }

    /**
     * Get totalSold
     *
     * @return Doctrine\Common\Collections\Collection $totalSold
     */
    public function getTotalSold() {
        return $this->total_sold;
    }

}

这是我的子文件。

    protected $created_at;

    /**

    protected $delta_totalsold;



    public function __construct()
    {

        }

    {
        $this->delta_totalsold = $dealtaTotalsold;
        return $this;
    }



    /**

}

必须使用$elemMatch运算符将数组元素中的多个组件与$and匹配。

db.deals.find({ total_sold: { $elemMatch : {
  $and:[ {created_at: {$gt: new ISODate("2014-03-05T00:00:00Z") }},
         { created_at: {$lt: new ISODate("2014-03-05T23:00:00Z") }}
        ]
  }}
});
