Query MongoDB + Redash

I need to make a query in Redash that generates a Ranking that is usually simple I do an unwind of what I want and use a sort to leave in the descending order, however now I need to make a query that has several "matches" within the matchs check the strings and depending on the string add +1 in a certain variable that will appear in the Ranking:

{
"collection": "data",

"aggregate": [
    {
        "$unwind": "$data.produtos"
    },
    {
        "$project": {
            "_id": "$data.produtos.nome"
        }
    },
    {
        "$match": {
            "_id": {
                "$in": [
                    "biscoito",
                    "brinquedo",
                    "picape",
                    "moto",
                    "piscina"
                ]
            }
        }
    },
    {
        "$group": {
            "_id": "$_id",
            "count": {
                "$sum": 1
            }
        }
    },
    {
        "$sort": [
            {
                "name": "count",
                "direction": -1
                }
            ]
        }
    ]
} 

In this example I basically need to do the following if the match is for the motorcycle or car, I put the variable that does not exist AUTOMOVEIS in the ranking and I'm adding in the counter
