Parsing query string with custom aggregation, using Search API

Elastic Stack Elasticsearch
1

I've installed a plugin to elastic (GitHub - opendatasoft/elasticsearch-aggregation-geoclustering: An Elasticsearch plugin to aggregate Geo Points in clusters.) and I have an endpoint (high level rest client) that takes an ES query body string and builds it with SearchSourceBuilder.

Using kibana, the plugin works fine:

{
  "size": 0,
  "query": {
    "match_all": {}
  },
  "aggs": {
    "clusters": {
      "geo_point_clustering": {
        "field": "geo.point",
        "zoom": 5
      }
    }
  }
}

And I get the expected result.

However, the SearchSourceBuilder have trouble parsing the "geo_point_clustering" aggregation

Exception:

threw exception [Request processing failed; nested exception is ParsingException[Unknown aggregation type [geo_point_clustering]]; nested: NamedObjectNotFoundException[[31:30] unknown field [geo_point_clustering]];] with root cause

The exception comes from where the request body is converted into a SearchSourceBuilder

val searchSourceBuilder = SearchSourceBuilder().timeout(TimeValue(5, TimeUnit.SECONDS))
val searchModule = SearchModule(Settings.EMPTY, false, emptyList())
val xContentRegistry = NamedXContentRegistry(searchModule.namedXContents)
searchSourceBuilder.parseXContent(
  XContentFactory.xContent(XContentType.JSON)
    .createParser(xContentRegistry,
      DeprecationHandler.THROW_UNSUPPORTED_OPERATION, body)
)

So my question is (i think) how can I add the custom aggregation type to this parser?

Thanks!

Hi.

I dont now if I to help but you can perform this way using query in format json:

I should've stated this in the post, but we're on v7.10. I'm also in particular interested in using SearchSourceBuilder. Thanks for the suggestion!
