Significant Terms Aggregation Usageedit

Fluent DSL Exampleedit

s => s
.Aggregations(a => a
    .SignificantTerms("significant_names", st => st
        .Field(p => p.Name)
        .MinimumDocumentCount(10)
        .MutualInformation(mi => mi
            .BackgroundIsSuperSet()
            .IncludeNegatives()
        )
    )
)

Object Initializer Syntax Exampleedit

new SearchRequest<Project>
{
    Aggregations = new SignificantTermsAggregation("significant_names")
    {
        Field = Field<Project>(p => p.Name),
        MinimumDocumentCount = 10,
        MutualInformation = new MutualInformationHeuristic
        {
            BackgroundIsSuperSet = true,
            IncludeNegatives = true
        }
    }
}
