Thanks Adrien, I'll take a look at the FloatPointNearestNeighbor implementation. Points are really an exciting feature! Joel Bernstein http://joelsolr.blogspot.com/ On Wed, Feb 7, 2018 at 8:53 AM, Adrien Grand wrote: > Hi Joel, > > You can search for nearest neighbors of a vector, see eg. Stev

Hi Joel, You can search for nearest neighbors of a vector, see eg. Steve's FloatPointNearestNeighbor in the sandbox. One important limitation is that it can only work on the whole index, ie. you can't find for the nearest neighbors to a point that also match a filter. If you want to do this, you w

I've been digging into the capabilities of the current points implementation in Lucene. The use case I'm interested in is K nearest neighbor search for vectors. The idea is to provide Lucene with a vector to search for, seek to a location in the TermsEnum that most closely matches the vector and t
