Add another one sorting to lift 3 docs to positions 3,4,5

I have a query with several sortings. Here is the sorting part:

    "sort": [
        "isHistorical",
        "_score",
        {
            "_script": {
                "type": "number",
                "script": {
                    "lang": "painless",
                    "source": "double score = 0; for (int i = 0; i < params.scalar_values.length; ++i) {     if (doc[params.scalar_values[i].field].value == params.scalar_values[i].value) {         score += params.scalar_values[i].score;     } } for (int i = 0; i < params.array_values.length; ++i) {     if (doc[params.array_values[i].field].contains(params.array_values[i].value)) {         score += params.array_values[i].score;     } } return score;",
                    "params": {
                        "scalar_values": [],
                        "array_values": []
                    }
                },
                "order": "desc"
            }
        },
        {
            "inStock": {
                "order": "desc"
            },
            "daysUntilReadinessForPickup": {
                "order": "asc"
            },
            "numberTradePointsForNearestPickup": {
                "order": "desc"
            },
            "availableInTradePointsCount": {
                "order": "desc"
            }
        }
    ]

After all sortings applied (and before limit) I want to add another sorting. It is related to prioritized documents.
Every doc has field "assortmentUnitId" of integer type. I have a list of assortmentUnitIds, each of them has sort order value. where sort order of 0 is the top priority. 1 is less, and so far.

assortmentUnitId = 123, sort order = 0
assortmentUnitId = 456, sort order = 1
assortmentUnitId = 789, sort order = 2
assortmentUnitId = 999, sort order = 5

I want to pass this map (assortmentUnitId => sortOrder) to the query so that
after applying all the other sortings these prioritized docs go up in the result list to the position 3, 4, 5 (not right at the beginning! :open_mouth: ). I'll be passing only 3 prioritized values to the query

Is it possible? Can you guide me how to achieve this? Should I give your the other parts of the request? Thanks

Sorry, my mistake. The big difficulty here is that I'll be probably passing more than 3 ids, but I need not more than 3 docs to float

Have you considered using the multi search API to send 2 separate queries, one for the query and one for the prioritised documents, and then merge the result sets client side? This is as far as I can recall the standard solution for the type of mixed sorting you are describing.
