Fluent DSL example

edit

s => s
.Size(0)
.Aggregations(aggs => aggs
    .AdjacencyMatrix("interactions", am => am
        .Filters(fs => fs
            .Filter("grpA", f => f.Term(p => p.State, StateOfBeing.BellyUp))
            .Filter("grpB", f => f.Term(p => p.State, StateOfBeing.Stable))
            .Filter("grpC", f => f.Term(p => p.State, StateOfBeing.VeryActive))
        )
    )
)

Object Initializer syntax example

edit

new SearchRequest<Project>
{
    Size = 0,
    Aggregations = new AdjacencyMatrixAggregation("interactions")
    {
        Filters = new NamedFiltersContainer
        {
            { "grpA", new TermQuery { Field = "state", Value = StateOfBeing.BellyUp } },
            { "grpB", new TermQuery { Field = "state", Value = StateOfBeing.Stable } },
            { "grpC", new TermQuery { Field = "state", Value = StateOfBeing.VeryActive } },
        }
    }
}

Handling Responses

edit

response.ShouldBeValid();
var interactions = response.Aggs.AdjacencyMatrix("interactions");
interactions.Should().NotBeNull();
var buckets = interactions.Buckets;
buckets.Should().NotBeNullOrEmpty();
foreach (var bucket in buckets)
{
    bucket.Key.Should().NotBeNullOrEmpty();
    bucket.DocCount.Should().BeGreaterThan(0);
}
