Hi all, Lucene is able to index generic n-dimensional points for efficient similarity or nearest neightbors search? I have looked at spatial package in the past but seems it is specific to geo points? The use case is to index image feature vectors to search for similar images in a corpus.
Currently we are using lucene to text search and we would like to not have to manage two different index structures, synchronize commits, so on. Thank you, Luis Nassif
