Michael, The realtime search code is more or less ready. It probably needs some more test cases related to multithreading. I could use some help in coming up with test cases as admittedly I struggle with them.
In terms of the native Lucene version, I think it may be useful to offer optimistic concurrency which would make the API slightly different than IndexWriter's add, delete, update document methods. The reason optimistic concurrency is needed is updating documents can become problematic without it in realtime. The API might look something like: addDocument() updateDocument(String id, long version, Document document) deleteDocument(String id) On Thu, Aug 21, 2008 at 5:42 AM, Michael McCandless < [EMAIL PROTECTED]> wrote: > > I agree: getting real-time search working natively in Lucene is an > important goal. > > I think as an immediate step we should get Ocean committed in contrib? > This way users can easily try it out, report back, etc. > > Ocean is nice in that it operates above Lucene's core (using > InstantiatedIndex/Reader to handle the "live" additions).
