Description
ClassicSimilarity was relying on coordination factors in order to produce good scores. Now that coords are gone, it is quite a bad option compared to eg. BM25Similarity.
Maybe we should remove ClassicSimilarity entirely in master and deprecated in 6.x in order to encourage users to move to BM25Similarity rather than stay on a Similarity impl of lesser quality?
