Digy commented on LUCENENET-415: -------------------------------- Hi Ben, A few points about test. 1- Enable caching & ensure that your queries are unique. Is this legitimate? 2- Make your test with 40 facets. You may see a huge difference between these approaches. 3- And the most important one, openBitSet.Cardinality is toooo slow. If you repeat the tests without "resultBitSet.Cardinality()", you will see the cost of it. I am trying to figure out how to handle this.
