Hi, Michael : True, the table is a placeholder right now. I will run my performance tests and update the table in the next day or two. Paul : Thanks for skimming over the code. As John mentioned in his email, we currently use Kamikaze for in memory caching for document hits. The Kamikaze proj

Re: docid set compression and boolean docid set operations

Hi guys: I will let the author, Anmol Bhasin to respond with details. In our use case, we are not making changes to the index because we do not want to diverge from the lucene code base. (thought it'd be great if we can enhance indexing structure with this) We load the docIdSets into memo

Re: docid set compression and boolean docid set operations

John, I've taken a first look at the code, and I have a few questions. Did I understand correctly that it is basically a two way conversion between an integer array and an (Open)BitSet representing a p4delta data structure? In that case it would still be necessary to extend the lucene index stru
