==== Percentile Ranks Aggregation

Here is how you can use
{ref}/search-aggregations-metrics-percentile-rank-aggregation.html[Percentile Ranks Aggregation]
with Java API.


===== Prepare aggregation request

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

[source,java]
--------------------------------------------------
MetricsAggregationBuilder aggregation =
        AggregationBuilders
                .percentileRanks("agg")
                .field("height")
                .percentiles(1.24, 1.91, 2.22);
--------------------------------------------------


===== Use aggregation response

Import Aggregation definition classes:

[source,java]
--------------------------------------------------
import org.elasticsearch.search.aggregations.metrics.percentiles.Percentile;
import org.elasticsearch.search.aggregations.metrics.percentiles.PercentileRanks;
--------------------------------------------------

[source,java]
--------------------------------------------------
// sr is here your SearchResponse object
PercentileRanks agg = sr.getAggregations().get("agg");
// For each entry
for (Percentile entry : agg) {
    double percent = entry.getPercent();    // Percent
    double value = entry.getValue();        // Value

    logger.info("percent [{}], value [{}]", percent, value);
}
--------------------------------------------------


This will basically produce:

[source,text]
--------------------------------------------------
percent [29.664353095090945], value [1.24]
percent [73.9335313461868], value [1.91]
percent [94.40095147327283], value [2.22]
--------------------------------------------------
