                }
            ]
        }
    ]
}

Я хочу только выбранные поля, если: идентификатор отеля 45, цена размещения 1, is_active равен false, статус "В ожидании" и тип плана в [«AP», «EP»]. Желаемый результат:

                }
            ]
        }, 
        {
            "plan_type" : "EP", 
            "sub_plans" : [

                                {
                                    "veg_price" : null, 
                                }
                            ]

                }
            ]
        }, 
    ]
}

Мой запрос: 

db.collection.find({
  "hotel_id": 45,
  "plans.plan_type": {$in : ["AP", "EP"]},
  "plans.sub_plans.channels.prices.occupancy": 1,
  "plans.sub_plans.channels.is_active": false,
  "plans.sub_plans.channels.status": "Pending"
})

Примечание - мне нужно искать только в одном документе с идентификатором отеля 45. Пожалуйста, помогите. Заранее спасибо.

Возможно, вы ищете такой запрос. 

db.collection.aggregate([
  {
    "$unwind": "$plans",

  },
  {
    "$group": {
      "_id": "$hotel_id",
      "hotel_id": {
        "$first": "$hotel_id"
      },
      "plans": {
        "$push": {
          "$cond": [
            {
              "$or": [
                {
                  "$eq": [
                    "$plans.plan_type",
                    "AP"
                  ]
                },

Вам необходимо применить агрегацию. 

db.collection_name.aggregate([

    {
        "$match":{
            "hotel_id": 45,
            "plans.plan_type": "AP",
            "plans.sub_plans.channels.prices.occupancy": 1,
            "plans.sub_plans.channels.is_active": false,
            "plans.sub_plans.channels.status": "Pending"
        }
    },
    {
        "$project":{
            "_id":"$_id",
            "hotel_id":"$hotel_id",
            "plans":"plans"
        }
    }
])
...
