I have a list of Buckets (parentSalaries) that has a list of Aggregations of size 2. One of the Aggregations (average\_salary) has the following fields; **value** , **name, valueAsString and metadata**. I am trying to extract the data from the " **value**" but there is no function for it. I tried to use other types of Aggregations such as `ParsedTDigestPercentiles but there is no function that can be used to extract the "value" data. Hopefully, someone can help me.

```auto
private void doSomething(Aggregations aggregations) {
 //aggregations is the Aggregations from the SearchResponse
 Terms parentSalaryRatio = aggregations.get("parent_salary_ratio");
 if (parentSalaryRatio != null) {
            List<? extends Terms.Bucket> parentSalaries = parentSalaryRatio.getBuckets();
            getTotalAvgSalaries(parentSalaries);
        }
}

 private void getTotalAvgSalaries(List<? extends Terms.Bucket> parentSalaries) {
      Aggregations aggregations = parentSalaries.get(0).getAggregations();
      Aggregation avgSalaryAgg = aggregations.get("avg_salary");
      //No function to get the "value" out of "avgSalaryAgg"

}

```

Query

```auto
 AggregationBuilder precentials_salary = AggregationBuilders
                .percentiles("precentials_salary")
                .field("perAnnumSalary");

```

```
    AggregationBuilder average_salary = AggregationBuilders
            .avg("average_salary")
            .field("perAnnumSalary");

```

Thanks

Welcome to our community! 😃

It'd be great if you could share your query and an example response so people can see exactly what you are referring to.

I used _ParsedSingleValueNumericMetricsAggregation_ to extract the "value" data. It has the _value()_ function. The _ParsedAvg_ can be used as well. It extends _ParsedSingleValueNumericMetricsAggregation_
