I'm working with an Elasticsearch index where I have a mapping that includes a nested field called `servicePrices` . Within this nested field, I'm trying to select the top 1 record based on a specific field such as `matches` and then filter the selected record based on another field such as `price` . Here's a simplified version of my mapping:

```auto
{
  "services": {
    "mappings": {
      "properties": {
        "id": {
          "type": "keyword"
        },
        "servicePrices": {
          "type": "nested",
          "properties": {
            "age": {
              "type": "float"
            },
            "gender": {
              "type": "float"
            },
            "matches": {
              "type": "float"
            },
            "price": {
              "type": "nested",
              "properties": {
                "amount": {
                  "type": "float"
                },
                "currency": {
                  "type": "keyword"
                }
              }
            }
            // Other nested properties...
          }
        }
      }
    }
  }
}

```

Could someone provide guidance on how to accomplish this selection, filtering, and inclusion of nested fields

Hi @Soso_Kapianidze :

If I understood correctly, you want to:

- Sort your results based on a nested field to get the top result
- Perform a search on the nested fields for selecting specific inner hits that match the search.

Both should be doable - please check the docs on:

- [Sorting nested objects](https://www.elastic.co/guide/en/elasticsearch/reference/current/sort-search-results.html#nested-sorting)
- [Nested inner hits](https://www.elastic.co/guide/en/elasticsearch/reference/current/inner-hits.html#nested-inner-hits) for retrieving the nested fields for a query

Hope that helps!
