/ 10 октября 2019

У меня проблема с возвратом документов, которых нет в списке условий.

Я пробовал несколько способов, но ни один не возвратил 13 предметов, которые они должны были вернуть.

В моей коллекции есть эти предметы( всего 17 ):

В этом запросе возвращает правильное значение ( 4 itens ): 

db.getCollection("vinculos").aggregate(
    [
        { 
            "$match" : {
                "status.codigo" : "1", 
                "tipo" : {
                    "$in" : [
                        "amizade",

Но мне нужнозначение, обратное этому итэнсу:

1-я попытка (без результатов) :

2-я попытка (без результатов) :

                            ]
                        }

                ]
            }
        }
    ]
)

Мне нужно будет вернуть еще 13 итенов, есть предложения?

Для дополнения фильтров мы можем использовать De Morgan's law, т. Е.

Not (A и B и C) = Not (A) или Not (B) или Not (C)

Следующий запрос может дать нам ожидаемый результат: 

db.getCollection("vinculos").aggregate(
    [
        { 
            "$match" : {
                $or:[
                    {
                        "status.codigo" :{
                            $ne: "1"
                        } 
                    }, 
                    {
                        "tipo" : {
                            "$nin" : [
                                "amizade", 
                                "nao-sugerir"
                            ]
                        }
                    }, 
                    {
                        "vinculo.objeto" : {
                            $ne: ObjectId("5d6821c70215c9e5e5fd096b")
                        }
                    }
                ]
            }
        }
    ]
