How to describe this aggregation using the Nest .NET Library?

Elastic Stack Elasticsearch
1

I have an aggregation that also has a filter and I am having trouble composing it with the .NET Nest Library:

{ "aggs": { "positive_lat": { "filter": { "bool": { "must_not": [ { "term": { "latitude": 0 } } ] } }, "aggs" : { "min_lat": { "min": { "field": "latitude" } } } } } }

How does one do something like that? Is it possible?

Yep, it's possible:

var client = new ElasticClient(); // use your document type instead of object var searchResponse = client.Search<object>(s => s .Aggregations(a => a .Filter("positive_lat", f => f .Filter(q => q .Bool(b => b .MustNot(mn => mn .Term("latitude", 0) ) ) ) .Aggregations(aa => aa .Min("min_lat", m => m .Field("latitude") ) ) ) ) ); // do something with min latitude var minLatitude = searchResponse.Aggregations.Filter("positive_lat").Min("min_lat").Value;

Take a look at the Writing Aggregations documentation, as well as the usage examples for aggregations.
