How to filter aggregated data on the nested object

[shri_palchuri]

Here is the payload used to filter the data, holdings is a nested type and in the aggregation it includes non matched count.

{"size":0,"query":{"bool":{"filter":[{"bool":{"filter":[{"bool":{"should":[{"bool":{"filter":[{"terms":{"keyInformation.enterpriseHandle":["XXXXXXXXXXXX"],"boost":1}}],"adjust_pure_negative":true,"boost":1}}],"adjust_pure_negative":true,"boost":1}},{"bool":{"filter":[{"bool":{"filter":[{"nested":{"query":{"bool":{"filter":[{"wildcard":{"holdings.parentStyle":{"wildcard":" *Commodities* ","case_insensitive":true,"boost":1}}}],"adjust_pure_negative":true,"boost":1}},"path":"holdings","ignore_unmapped":false,"score_mode":"max","boost":1}}],"adjust_pure_negative":true,"boost":1}}],"adjust_pure_negative":true,"boost":1}}],"adjust_pure_negative":true,"boost":1}}],"adjust_pure_negative":true,"boost":1}},"_source":{"includes":["keyInformation.portfolioHandle"],"excludes":[]},"aggregations":{"parentStyle":{"nested":{"path":"holdings"},"aggregations":{"parentStyle":{"composite":{"size":600,"sources":[{"parentStyle":{"terms":{"field":"holdings.parentStyle","missing_bucket":false,"order":"asc"}}}]},"aggregations":{"count":{"reverse_nested":{},"aggregations":{"count":{"value_count":{"field":"keyInformation.portfolioHandle"}}}}}}}}}}

Output:

"aggregations" : {
    "parentStyle" : {
      "doc_count" : 204,
      "parentStyle" : {
        "after_key" : {
          "parentStyle" : "U.S. Stocks"
        },
        "buckets" : [
          
          {
            "key" : {
              "parentStyle" : "Cash"
            },
            "doc_count" : 16,
            "count" : {
              "doc_count" : 14,
              "count" : {
                "value" : 14
              }
            }
          },
          {
            "key" : {
              "parentStyle" : "Commodities"
            },
            "doc_count" : 23,
            "count" : {
              "doc_count" : 14,
              "count" : {
                "value" : 14
              }
            }
          },
          {
            "key" : {
              "parentStyle" : "U.S. Stocks"
            },
            "doc_count" : 81,
            "count" : {
              "doc_count" : 14,
              "count" : {
                "value" : 14
              }
            }
          }
        ]
      }
    }
  }
}

But I am looking to return count only for "parentStyle" : "Commodities", how can I achieve this?
