Description

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.
