: Yonik, Erik... : What would be the right way to put ObenBitSet into Lucene?
I think the right thing to do is put it in Solr since there's a demonstrated use for it there. if/when it makes sense to "promote" it into Lucene core we can do that -- but at the moment there really isn't ... the only place BitSets are used in Lucene is in Filters, and the current push is to remove that API usage favor of an iterator style approach. At that point, it may make sense for people to impliment Filters under the covers with OpenBitSets .. but untill that time comes, Solr seems like the place to put it. -Hoss
