Referring to our private conversation with Alexander Korotkov, the
patch is in WIP state currently, and, hopefully, will be ready by 9.5.
I'm ready to actively participate in its testing on a real world
production set of data.
I'm not sure if it is doable at all, but are there any possibility to
implement here, or, what would be just great, any ready/half ready
solutions of a Hamming distance based kNN search?
