Global aggregation

edit

Global aggregation

edit

Defines a single bucket of all the documents within the search execution context. This context is defined by the indices and the document types you’re searching on, but is not influenced by the search query itself.

Fluent DSL

edit

var result = client.Search<ElasticsearchProject>(s => s
    .Query(q => q
        .Match(m => m
            .OnField(p => p.Country)
            .Query("Malaysia")))
    .Aggregations(a => a
        .Global("global_bucket", d => d
            .Aggregations(aa => aa
                .Terms("bool_count", t => t
                    .Field(f => f.BoolValue)
                )
            )
        )
    )
);

var agg = result.Aggs.Global("global_bucket");
var bools = agg.Terms("bool_count");

Object Initializer Syntax

var request = new SearchRequest
{
    Query = new QueryContainer(new MatchQuery
    {
        Field = "country",
        Query = "Malaysia"
    }),
    Aggregations = new Dictionary<string, IAggregationContainer>
    {
        { "global_bucket", new AggregationContainer
            {
                Global = new GlobalAggregator(),
                Aggregations = new Dictionary<string, IAggregationContainer>
                {
                    { "bool_count", new AggregationContainer
                        {
                            Terms = new TermsAggregator
                            {
                                Field = "boolValue"
                            }
                        }
                    }
                }
            }
        }
    }

var agg = result.Aggs.Global("global_bucket");
var bools = agg.Terms("bool_count");
