Percentiles Bucket Aggregation Usageedit

Fluent DSL exampleedit

s => 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)
            )
        )
    )
    .PercentilesBucket("commits_outlier", aaa => aaa
        .BucketsPath("projects_started_per_month>commits")
        .Percents(95, 99, 99.9)
    )
)

Object Initializer syntax exampleedit

new SearchRequest<Project>()
{
    Size = 0,
    Aggregations = new DateHistogramAggregation("projects_started_per_month")
    {
        Field = "startedOn",
        Interval = DateInterval.Month,
        Aggregations = new SumAggregation("commits", "numberOfCommits")
    }
    && new PercentilesBucketAggregation("commits_outlier", "projects_started_per_month>commits")
    {
        Percents = new[] { 95, 99, 99.9 }
    }
}

Handling Responsesedit

response.ShouldBeValid();

var projectsPerMonth = response.Aggs.DateHistogram("projects_started_per_month");
projectsPerMonth.Should().NotBeNull();
projectsPerMonth.Buckets.Should().NotBeNull();
projectsPerMonth.Buckets.Count.Should().BeGreaterThan(0);

var commitsOutlier = response.Aggs.PercentilesBucket("commits_outlier");
commitsOutlier.Should().NotBeNull();
commitsOutlier.Items.Should().NotBeNullOrEmpty();
foreach (var item in commitsOutlier.Items)
    item.Value.Should().BeGreaterThan(0);
