I have this Elasticsearch NEST query:
var res = elastic.Search<SegmentRecord>(s => s.Index(esIndex).Aggregations(a => a.Terms("agg", x => x.Field(o => o.InstrumentName).Aggregations(a1 => a1.Terms("agg2", f => f.Field(y => y.GroupId))))));
how can I cycle through all the InstrumentName
fields, and for each of those, cycle through all the GroupId
fields?
On Nest 5.4.0
foreach (var bucket in res.Aggs.Terms("agg").Buckets)
{
foreach (var innerBucket in bucket.Terms("agg2").Buckets)
{
System.Console.WriteLine($"agg:{bucket.Key}, agg2:{innerBucket.Key} - {innerBucket.DocCount}");
}
}
This is how I accessed my children buckets with nested aggregations.
var yourAgg = result.Aggregations.Terms("YourParentField");
foreach (var child in yourAgg .Buckets)
{
var aggs = child.Terms("YourChildField").Buckets;
foreach (var item in aggs)
{
perDealerAggItems.Add(new AggregateItem()
{
Count = item.DocCount ?? 0,
Key = item.Key,
ParentList = field
});
}
}
