Hi all, I'm currently using Solr and I've got a question about filtering on a lower level than filter queries. We want to be able to restrict the documents that can possibly be returned to a users query. From another system we'll get a list of document unique ids for the user which is all the documents that they can possibly see (i.e. a base index list as such). The criteria for what document ids get returned is going to be quite flexible. As the number of ids can be up to index size - 1 (i.e. thousands) using a filter query doesn't seem right for entering a filter query which is so large. Can something be done at a lower level - perhaps at a Lucene level - as I understand Lucene starts from a bitset of possible documents it can return - could we AND this with a filter bitset returned from the other system? Would this be a good way forward? And then how would you do this in Solr with still keeping Solr's extra functionality it brings over Lucene. A new SearchHandler? Thanks Mike
