The query conditions are too complex

[shzy2012]

Can it be simplified, such as supporting map?

json format

POST /collections/chatapp/points/delete
{
    "filter": {
        "must": [
            {
                "key": "source",
                "match": {
                    "value": "example.pdf"
                }
            }
        ]
    }
}
