Hi,

I'm trying to use the Java API to do insert/updates for nested documents. I have a collection with products and the nested documents are offers. Doing this via a json request works fine:  
{  
"script" : "ctx.\_source.offer=offer",  
"params" : {  
"offer": {"price": 20}  
}  
}

However using the java API is not that trivial, i tried the example in:

> <https://stackoverflow.com/questions/23363801/update-nested-field-in-an-index-of-elasticsearch-with-java-api>

  
but can't get it to work. There is a setScript() method but not a setScriptParameter() method.

So what i have now is:  
UpdateRequestBuilder br = client.prepareUpdate(INDEXNAME, DOCUMENT\_TYPE, PRODUCT\_ID);  
build a json string  
br.setScript(new Script("ctx.\_source.offer = offer"));  
but i can't add the json string anywhere and the documentation seems void of an example.

I use elasticsearch 2.0.0, java 8, windows 7

Hope someone has an idea on how to do this with the Java API.

Thanks,  
Maarten
