Sum Bucket Aggregation Usage
editSum Bucket Aggregation Usage
editFluent DSL example
edits => s .Size(0) .Aggregations(a => 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) ) ) ) .SumBucket("sum_of_commits", aaa => aaa .BucketsPath("projects_started_per_month>commits") ) )
Object Initializer syntax example
editnew SearchRequest<Project>() { Size = 0, Aggregations = new DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", Interval = DateInterval.Month, Aggregations = new SumAggregation("commits", "numberOfCommits") } && new SumBucketAggregation("sum_of_commits", "projects_started_per_month>commits") }
Example json output.
{ "size": 0, "aggs": { "projects_started_per_month": { "date_histogram": { "field": "startedOn", "interval": "month" }, "aggs": { "commits": { "sum": { "field": "numberOfCommits" } } } }, "sum_of_commits": { "sum_bucket": { "buckets_path": "projects_started_per_month>commits" } } } }
Handling Responses
editresponse.IsValid.Should().BeTrue(); var projectsPerMonth = response.Aggs.DateHistogram("projects_started_per_month"); projectsPerMonth.Should().NotBeNull(); projectsPerMonth.Buckets.Should().NotBeNull(); projectsPerMonth.Buckets.Count.Should().BeGreaterThan(0); var commitsSum = response.Aggs.SumBucket("sum_of_commits"); commitsSum.Should().NotBeNull(); commitsSum.Value.Should().BeGreaterThan(0);
