我的MongoDB json数组看起来像这样：

    "_id" : ObjectId("56c1770ad857b64e379af41c"),
    "UUID" : "75a29021-9cc2-4896-934b-471fc4c7c3da",

            }, 
            {

                "Body" : "Stikadapter"
            },

                "Body" : "P/N: 0A001-00230000"
            }
        ],
        "Full" : [ 
            {
                "Header" : "Type",

            }, 
            {

            }, 
            {
                "Header" : "Lokalisering",
                "Body" : "Storbritannien"
            }, 
            {
                "Header" : "Designet for",
                "Body" : "P/N: 0A001-00230000"
            }
        ],
        "Search" : [ 
            {
                "HeaderID" : "T0000010",
                "Body" : "Stikadapter"
            }, 
            {
                "HeaderID" : "T0000087",
                "Body" : "Sort"
            }, 
            {
                "HeaderID" : "T0005917",
                "Body" : "Sort"
            }, 
            {
                "HeaderID" : "T0000046",
                "Body" : "Storbritannien"
            }, 
            {
                "HeaderID" : "T0003807",
                "Body" : "P/N: 0A001-00230000"
            }
        ]
    }
}

我想要搜索的内容是HeaderID和Body上的Specifications -> Full。

我的问题我只能使用$elemMatch一次，我在php中使用find命令以及我想在其之后搜索的内容

查找匹配的所有产品

HeaderID = T0000087 and Body = Black, White or Yello AND
HeaderID = T0000087 and Body = UK, USA or DK

我的搜索过滤器看起来像这样，因为我现在测试它不能正常工作！

$this->_searchFilter = [
    'Category' => $this->categoryUUID,
    'Store.AllowDisplay' => '1',
    'Store.Activated' => '1',
    'Specifications.Search' => [
        ['$elemMatch' => [
            'HeaderID' => 'T0000010',
            'Body' => 'USB-kabel'
        ]],
        ['$elemMatch' => [
            'HeaderID' => 'T0000087',
            'Body' => 'Brunsort'
        ]]
    ]
];

我的调试MongoDB看起来像这样

db.getCollection('product').find({ "Specifications.Search": { $elemMatch: { 'HeaderID' : 'T0000010', 'Body' : "Stikadapter"}}})

Answer 1

我找到了awsare，我想要的是使用$和$ $和多$ elemMatch，我的代码看起来像这样。

db.getCollection('product').find({
    $and: [{ 
        $or :[{
            "Specifications.Search": { 
                $elemMatch: { 
                    'HeaderID' : 'T0000010', 
                    'Body' : "Stik"
                }
            }
        }, {
            "Specifications.Search": { 
                $elemMatch: { 
                    'HeaderID' : 'T0000010', 
                    'Body' : "Stikadapter"
                }
            }
        }]
    }]
})

在php中使用Mongo多$ elemMatch
