> In machine learning problems we usually need to find nearest neighbors in 
> dense high dimensional vector space. Often, this retrieval had to be 
> augmented with traditional Boolean retrieval.
> While no efficient KNN implementation is available in Solr yet, in practice 
> people are using brute-force vector distance sorting after Boolean retrieval 
> limits number of candidate vectors.
> It's proposed to add a clear way to implement such a solution with Solr.
