   > I get 10-20% faster search and ~4x smaller storage used for the search (I am keeping the raw vectors around...we can debate if we want to do that)
   
   @benwtrent Based on your comments, does 4x smaller storage means optimization in terms of disk space or the memory savings(RAM). Can you please confirm and how did you run these benchmarkings (the tool used) and how did you conclude that we are saving x% of memory savings. The reason being when I tried to integrate lucene with my service I was not able to see the same amount of memory savings during search.
