Bucket Script Aggregation Usage
editBucket Script Aggregation Usage
editFluent DSL example
edita => a .DateHistogram("projects_started_per_month", dh => dh .Field(p => p.StartedOn) .Interval(DateInterval.Month) .MinimumDocumentCount(1) .Aggregations(aa => aa .Sum("commits", sm => sm .Field(p => p.NumberOfCommits) ) .Filter("stable_state", f => f .Filter(ff => ff .Term(p => p.State, "Stable") ) .Aggregations(aaa => aaa .Sum("commits", sm => sm .Field(p => p.NumberOfCommits) ) ) ) .BucketScript("stable_percentage", bs => bs .BucketsPath(bp => bp .Add("totalCommits", "commits") .Add("stableCommits", "stable_state>commits") ) .Script(ss => ss.Source("params.stableCommits / params.totalCommits * 100")) ) ) )
Object Initializer syntax example
editnew DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", Interval = DateInterval.Month, MinimumDocumentCount = 1, Aggregations = new SumAggregation("commits", "numberOfCommits") && new FilterAggregation("stable_state") { Filter = new TermQuery { Field = "state", Value = "Stable" }, Aggregations = new SumAggregation("commits", "numberOfCommits") } && new BucketScriptAggregation("stable_percentage", new MultiBucketsPath { { "totalCommits", "commits" }, { "stableCommits", "stable_state>commits" } }) { Script = new InlineScript("params.stableCommits / params.totalCommits * 100") } }

Handling Responses
editresponse.ShouldBeValid(); var projectsPerMonth = response.Aggregations.DateHistogram("projects_started_per_month"); projectsPerMonth.Should().NotBeNull(); projectsPerMonth.Buckets.Should().NotBeNull(); projectsPerMonth.Buckets.Count.Should().BeGreaterThan(0); foreach (var item in projectsPerMonth.Buckets) { var stablePercentage = item.BucketScript("stable_percentage"); stablePercentage.Should().NotBeNull(); stablePercentage.Value.Should().HaveValue(); }
