Wie wendet man in MongoDb interne Sortierfelder an, die im Dokument vorhanden sind?

Dazu müssten Sie das Aggregation Framework verwenden

dies kehrt zurück

"result" : [
    {
            "_id" : ObjectId("5139ba3dcd4e11c83f4cea12"),
            "field1" : "somevalue",
            "name" : "xtz",
            "nested_documents" : {
                    "x" : "-1",
                    "y" : "3"
            }
    },
    {
            "_id" : ObjectId("5139ba3dcd4e11c83f4cea12"),
            "field1" : "somevalue",
            "name" : "xtz",
            "nested_documents" : {
                    "x" : "1",
                    "y" : "2"
            }
    },
    {
            "_id" : ObjectId("5139ba3dcd4e11c83f4cea12"),
            "field1" : "somevalue",
            "name" : "xtz",
            "nested_documents" : {
                    "x" : "2",
                    "y" : "3"
            }
    }
],
"ok" : 1

Hoffe das hilft
