===== Prepare aggregation request

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

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


===== Use aggregation response

Import Aggregation definition classes:

[source,java]
--------------------------------------------------
import org.elasticsearch.search.aggregations.metrics.max.Max;
--------------------------------------------------

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