==== Cardinality Aggregation

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


===== Prepare aggregation request

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

[source,java]
--------------------------------------------------
GeoBoundsBuilder aggregation =
        AggregationBuilders
                .geoBounds("agg")
                .field("address.location")
                .wrapLongitude(true);
--------------------------------------------------


===== Use aggregation response

Import Aggregation definition classes:

[source,java]
--------------------------------------------------
import org.elasticsearch.search.aggregations.metrics.geobounds.GeoBounds;
--------------------------------------------------

[source,java]
--------------------------------------------------
// sr is here your SearchResponse object
GeoBounds agg = sr.getAggregations().get("agg");
GeoPoint bottomRight = agg.bottomRight();
GeoPoint topLeft = agg.topLeft();
logger.info("bottomRight {}, topLeft {}", bottomRight, topLeft);
--------------------------------------------------

This will basically produce:

[source,text]
--------------------------------------------------
bottomRight [40.70500764381921, 13.952946866893775], topLeft [53.49603022435221, -4.190029308156676]
--------------------------------------------------
