Specifies percentile statistics of the aggregation feature in search indexes. A percentile value indicates the relative position of a value in a dataset. For example, when you collect statistics for the response time of each request during the routine O&M of your system, you must analyze the response time distribution by using percentiles such as p25, p50, p90, and p99.
