Delay in response after using function_score for sorting of documents according to field match

[AshuCh (Ashu)]

When using function_score to sort the document on base of score response is taking too much time to come it's in minutes. The problem is I need sorting according to fields. When using boost not getting the relevant data.

query I'm using is as follow:

function_score.functions[
/********* registered indian user exact match ********/
        {
          "filter": {
            "bool": {
              "must": [

                  "exists": {
                    "field": "userId"
                  }
                },
                {
