Hi Upayavira, This is news to me that we should not optimize and index.
What about disk space saving, isn't optimization to reclaim disk space or is Solr somehow does that? Where can I read more about this? I'm on Solr 5.1.0 (may switch to 5.2.1) Thanks Steve On Mon, Jun 29, 2015 at 4:16 AM, Upayavira <u...@odoko.co.uk> wrote: > I'm afraid I don't understand.
