Arrays 在Mongo中搜索对象数组以查找数组中包含的任何值

我正在尝试搜索Mongo，以查看数组中是否有任何字符串正在我的“images.src.large”中使用：

要搜索的字符串：

['/california/los-angeles/pool.jpg','/california/los-angeles/pizza.jpg']

我的Mongo系列的样本：

{
    "_id": someNumber,
    "name: "Name 1",
    "images": [
        {
            "title": "Title 1",
            "src": {
                "small": "/california/los-angeles/pool-small.jpg",
                "medium": "/california/los-angeles/pool-medium.jpg",
                "large": "/california/los-angeles/pool.jpg"
            }
        },
        {
            "title": "Title 2",
            "src": {
                "small": "/california/los-angeles/oven-small.jpg",
                "medium": "/california/los-angeles/oven-medium.jpg",
                "large": "/california/los-angeles/oven.jpg"
            }
        }
    ],
},
{
    "_id": someOtherNumber,
    "name: "Name 2",
    "images": [
        {
            "title": "Landscape",
            "src": {
                "small": "/alaska/badger/dog-small.jpg",
                "medium": "/alaska/badger/dog-medium.jpg",
                "large": "/alaska/badger/dog.jpg"
            }
        },
        {
            "title": "Food",
            "src": {
                "small": "/alaska/badger/pizza-small.jpg",
                "medium": "/alaska/badger/pizza-medium.jpg",
                "large": "/alaska/badger/pizza.jpg"
            }
        }
    ],
},
{
    "_id": aDifferentNumber,
    "name: "Bridge",
    "images": [
        {
            "title": "Store",
            "src": {
                "small": "/hawaii/kilauea/pool-small.jpg",
                "medium": "/hawaii/kilauea/pool-medium.jpg",
                "large": "/hawaii/kilauea/pool.jpg"
            }
        },
        {
            "title": "Home",
            "src": {
                "small": "/hawaii/kilauea/tree-small.jpg",
                "medium": "/hawaii/kilauea/tree-medium.jpg",
                "large": "/hawaii/kilauea/tree.jpg"
            }
        }
    ],
},

基本上，我试图通过使用文档中描述的

$in

操作符搜索“images.src.large”的值来搜索我的收藏，查看是否正在使用图像。您可以查询字段中的任意值。因此，示例文档中的以下查询将得到以下结果

> db.images.find({ "images.src.large" :
      { "$in" : ["/california/los-angeles/pool.jpg",
                 "/california/los-angeles/pizza.jpg"]
      }
  }).pretty();

{
    "_id" : 1,
    "name" : "Name 1",
    "images" : [
        {
            "title" : "Title 1",
            "src" : {
                "small" : "/california/los-angeles/pool-small.jpg",
                "medium" : "/california/los-angeles/pool-medium.jpg",
                "large" : "/california/los-angeles/pool.jpg"
            }
        },
        {
            "title" : "Title 2",
            "src" : {
                "small" : "/california/los-angeles/oven-small.jpg",
                "medium" : "/california/los-angeles/oven-medium.jpg",
                "large" : "/california/los-angeles/oven.jpg"
            }
        }
    ]
}

请注意，由于两个图像都在同一文档中使用，因此查询只返回一个文档。如果包含另一个文档中存在的值，则查询将返回两个文档。例如：

> db.images.count({ "images.src.large" :
      { "$in" : ["/california/los-angeles/pool.jpg",
                 "/alaska/badger/dog.jpg"]
      }
  });
