How to query nested attributes in Mongo?

Question

MongoDB

I have the following data set:

{
    "_id" : ObjectId("55d48d91e9fb6a71188b4567"),
    "data" : {
        "10104" : {
            "title" : "Abgasanlage/Turbolader/Lambda-Sonde ",
            "sort_title" : "abgasanlage/turbolader/lambda-sonde ",
            "node_id" : "10104",
            "parent_id" : "10001",
            "items" : [ 
                {
                    "assemblyGroupNodeId" : "12551",
                    "parentNodeId" : "10104",
                    "assemblyGroupName" : "Abgasklappe",
                    "alias" : "abgasklappe",
                }, 
//....
}

I'm trying to make a request - pull all records with assemblyGroupNodeId : 12551

db.collection.find({"data.items.assemblyGroupNodeId": "12551"})

Does not work. Can anyone come across?

Answer 1

Data has no items
Data has 10104 which has items

Answer 2

Here the guys suggest (@bingo347) that you can specify a more accurate index.
And without it it is impossible? just in my case 10104 is just what you are looking for
