Extended Stats Bucket Aggregation Usage
editExtended Stats Bucket Aggregation Usage
editFluent DSL example
edita => a .DateHistogram("projects_started_per_month", dh => dh .Field(p => p.StartedOn) .Interval(DateInterval.Month) .Aggregations(aa => aa .Sum("commits", sm => sm .Field(p => p.NumberOfCommits) ) ) ) .ExtendedStatsBucket("extended_stats_commits_per_month", aaa => aaa .BucketsPath("projects_started_per_month>commits") .Sigma(2.0) )
Object Initializer syntax example
editnew DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", Interval = DateInterval.Month, Aggregations = new SumAggregation("commits", "numberOfCommits") } && new ExtendedStatsBucketAggregation("extended_stats_commits_per_month", "projects_started_per_month>commits") { Sigma = 2.0 }
Example json output.
