I have been trying for hours to get this working. Basically I have a class  
that performs a aggregation and I want the user to be able to pass a  
JSON aggregatoin string to my constructor and then use that on the aggregation  
to further reduce the results. I have tried all manner of AggregationBuilders  
methods and SearchRequestBuilder methods.
