I have a java app that makes use of the SearchRequestBuilder. Usually I perform the operation using this pseudocode:

SearchRequestBuilder sb;  
AggregationBuilder agBuilder;  
//omitted some boiler plate where these are instantiatehow

sb.addAggregation(agBuilder);

I have a requirement whereby the aggregations part of the query is in the form of a json string. I need to add it to the SearchRequestBuilder somehow. Is there a recommended way to do this ?

I thought I might be able to achieve it via the XContentBuilder , but I'm not sure if it's possible to add the results of this to a SearchRequestBuilder anymore, so I'm looking for suggestions. (and I was rather hoping there was a quicker way than me creating the boiler plate to work through the json and turn it into an AggregationBuilder myself) 🙂

Many thanks,  
Phil

My question is essentially the same as this one:

> Hi everyone, My code has an ElasticSearch query and aggregations in JSON format, and wants to call the ElasticSearch Java API. For the Query portion, I can use WrapperQuery to build the query from the JSON as so: val query = Json.obj( "query\_string" -\> Json.obj("query" -\> "\*")) val aggs = Json.obj( "gender" -\> Json.obj("terms" -\> Json.obj("field": "gender")), "age" -\> Json.obj("terms" -\> Json.obj("field": "age"))) val aggsRequestBuilder = new SearchRequestBuilder(client) .setIndi…

I presume the answer is the same ?
