> Interleaving is an approach to Online Search Quality evaluation that can be 
> very useful for Learning To Rank models:

> Scope of this issue is to introduce the ability to the LTR query parser of 
> accepting multiple models (2 to start with).
> If one model is passed, normal reranking happens.
> If two models are passed, reranking happens for both models and the final 
> reranked list is the interleaved sequence of results coming from the two 
> models lists.
> As a first step it is going to be implemented through:
> TeamDraft Interleaving with two models in input.
> In the future, we can expand the functionality adding the interleaving 
> algorithm as a parameter.
