Sampler Aggregation Usageedit
Fluent DSL exampleedit
s => s .Aggregations(aggs => aggs .Sampler("sample", sm => sm .ShardSize(200) .Aggregations(aa => aa .SignificantTerms("significant_names", st => st .Field(p => p.Name) ) ) ) )
Object Initializer syntax exampleedit
new SearchRequest<Project> { Aggregations = new SamplerAggregation("sample") { ShardSize = 200, Aggregations = new SignificantTermsAggregation("significant_names") { Field = "name" } } }
Example json output.
{ "aggs": { "sample": { "sampler": { "shard_size": 200 }, "aggs": { "significant_names": { "significant_terms": { "field": "name" } } } } } }
Handling Responsesedit
response.ShouldBeValid(); var sample = response.Aggs.Sampler("sample"); sample.Should().NotBeNull(); var sigTags = sample.SignificantTerms("significant_names"); sigTags.Should().NotBeNull(); sigTags.DocCount.Should().BeGreaterThan(0); if (TestConfiguration.Instance.InRange(">=5.5.0")) sigTags.BgCount.Should().BeGreaterThan(0);
