> I have been very interested in the [Normalized Discounted Cumulative Gain|https://en.wikipedia.org/wiki/Discounted_cumulative_gain]
(nDCG) algorithm for addressing problems within the domain of federated web search. I am very
keen to get a working example/tutorial and implement nDCG within Gora which would extend the
work I did on using Gora as a query broking device. 
> This issue will implement a tutorial for ... using Gora as a query broker within a federated
search scenario with the emphasis being on utilization of our FilterList API's.
