Hi Mikhail, I'm not sure about the state of ANN in lucene proper. Very interested to see the response from others. I've been doing some work on ANN for an Elasticsearch plugin: http://elastiknn.klibisz.com/ I think it's possible to extract my custom queries and modeling code so that it's elasticsearch-agnostic and can be used directly in Lucene apps. However I'm much more familiar with Elasticsearch's APIs and usage/testing patterns than I am with raw Lucene, so I'd likely need to get some help from the Lucene community. Please LMK if that sounds interesting to anyone.
