title: How to get nested json object/value in scala
body: <p>I have Elasticsearch Search response that is a deeply nested Json file and I am stuck as to how to get a particular value from it.  Please am new to Scala and programming in general and I have searched online and could not see any answer that explained it well.
  This is the Json file and the value I want to get out is "getSum":"value"</p>
  
  <pre><code>Search_response: org.elasticsearch.action.search.SearchResponse = {

  <p>This is what I tried<br>
  val getResult: String = searchResult.toString.stripMargin
  val getValue = JsonParser.parse(getResult).asInstanceOf[JObject].values("aggregations").toString</p>
