==== 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]
|
||
|
