Bucket Selector Aggregation Usage
editBucket Selector 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) ) .BucketSelector("commits_bucket_filter", bs => bs .BucketsPath(bp => bp .Add("totalCommits", "commits") ) .Script(ss => ss.Source("params.totalCommits >= 500")) ) ) )
Object Initializer syntax example
editnew DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", Interval = DateInterval.Month, Aggregations = new SumAggregation("commits", "numberOfCommits") && new BucketSelectorAggregation("commits_bucket_filter", new MultiBucketsPath { { "totalCommits", "commits" }, }) { Script = new InlineScript("params.totalCommits >= 500") } }
Example json output.
{ "projects_started_per_month": { "date_histogram": { "field": "startedOn", "interval": "month" }, "aggs": { "commits": { "sum": { "field": "numberOfCommits" } }, "commits_bucket_filter": { "bucket_selector": { "buckets_path": { "totalCommits": "commits" }, "script": { "source": "params.totalCommits >= 500" } } } } } }
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 commits = item.Sum("commits"); commits.Should().NotBeNull(); commits.Value.Should().BeGreaterOrEqualTo(500); }
