==== Sum Aggregation

Here is how you can use
{ref}/search-aggregations-metrics-sum-aggregation.html[Sum Aggregation]
with Java API.


===== Prepare aggregation request

Here is an example on how to create the aggregation request:

[source,java]
--------------------------------------------------
SumAggregationBuilder aggregation =
        AggregationBuilders
                .sum("agg")
                .field("height");
--------------------------------------------------


===== Use aggregation response

Import Aggregation definition classes:

[source,java]
--------------------------------------------------
import org.elasticsearch.search.aggregations.metrics.sum.Sum;
--------------------------------------------------

[source,java]
--------------------------------------------------
// sr is here your SearchResponse object
Sum agg = sr.getAggregations().get("agg");
double value = agg.getValue();
--------------------------------------------------
