# Percentiles Aggregation
> More info about percentiles aggregation is in the [official elasticsearch docs][1]
A multi-value metrics aggregation that calculates one or more percentiles over
numeric values extracted from the aggregated documents.
## Simple example
```JSON
{
"aggregations" : {
"load_time_outlier" : {
"percentiles" : {
"field" : "load_time"
}
}
}
}
```
And now the query via DSL:
```php
$percentilesAggregation = new PercentilesAggregation('load_time_outlier', 'load_time');
$search = new Search();
$search->addAggregation($percentilesAggregation);
$queryArray = $search->toArray();
```
