GET my_index/_search
{
"from": 0,
"size": 10,
"query": {

    "bool": {
        "must": [
            {
                "match": {
                    "Id": "xxxxx"
                }
            }
        ],
        "filter": [
            {
                "nested": {
                    "path": "names",
                    "query": {
                     
                        "bool": {
                            "should": [
                                {
                                    "match": {
                                        "names.name": {
                                            "query": "Jon wick"
                                            //"fuzziness": "AUTO"
                                        }
                                    }
                                }
                            ]
                        }
                      
                    
                    }
                    
                }
            }
        ]
    
    
  }
},

     

"_source": [
    "partyId",
    "isSearchable"

]

}

Result:
I am getting sult like below :{
"_index": "my_index",
"_id": "1",
"_score": 0.023666047,
"_source": {}
},
{
"_index": "my_index",
"_id": "2",
"_score": 0.023666047,
"_source": {}
},

It's because you are matching only on Id.
The filter part only excludes what is not matching the filter without any effect on the score.
If you want to change that, put everything in the must part.
