Currently, we use the following api to do the nested sorting:

SortBuilders
      .fieldSort(variableValuePath) 
      .setNestedPath(variablePath)
      .setNestedFilter(termQuery(variableIdPath, inputVariableId))
      .order(sortOrder);

However, the setNestedPath and setNestedFiltersetNestedFilter methods are deprecated and should be replaced by setNestedSort method.

AT:

• the deprecated nested sorting api is replaced by the new one for raw decision data and raw process data reports
