I am new to ElasticSearch. I want to write a simple aggregation query using NEST in asp.net. How to write this simple query

GET /_search

 "aggs" : 
 "genres" : 
 "terms" : "field" : "genre" 
 
 

I started something like this:

var response = _connection.Get<ElasticClient>().Search<JObject>(s =>

Thanks

Started writing a comment, but maybe let's put it as an answer :)

Here are the docs for writing aggregations using NEST syntax.

As the example shows, for this sample aggregation:

 "aggs": 
 "name_of_child_agg": 
 "children": 
 "type": "commits"
 ,
 "aggs": 
 "average_per_child": 
 "avg": 
 "field": "confidenceFactor"
 
 ,
 "max_per_child": 
 "max": 
 "field": "confidenceFactor"
 
 ,
 "min_per_child": 
 "min": 
 "field": "confidenceFactor"
 
 
 
 
 

you can write this NEST fluent code:

s => s
.Aggregations(aggs => aggs
 .Children<CommitActivity>("name_of_child_agg", child => child
 .Aggregations(childAggs => childAggs
 .Average("average_per_child", avg => avg.Field(p => p.ConfidenceFactor))
 .Max("max_per_child", avg => avg.Field(p => p.ConfidenceFactor))
 .Min("min_per_child", avg => avg.Field(p => p.ConfidenceFactor))
 )
 )
)

Also, I don't think you want to use JObject type as POCO, this should put some light on how to use your custom type to map c# class into elasticsearch type. The reasoning behind: to have type responsible only for "communicating" with elasticsearch, so having JObject in this role may not the best option, as it's not a type created by you and it may evolve in the future in the way you don't want.
