I have a situation in which I can't safely optimize, the index is on a machine that doesn't have enough disk space. I have no control over the hardware. There are some raw statistics on this index that don't make sense, it's roughly twice the size of a similar index (could be legit, but it seems out of whack). And the number of deleted documents isn't big enough to account for the discrepancy.
So is there a good way, without optimizing, to purge any segments not referenced in the segments file? Actually I doubt that optimizing would even do it if I _could_, any phantom segments aren't visible from the segments file anyway... I can generate a list of active segments using CheckIndex and compare that against the contents of the index directory right enough, and remove the segments that aren't listed, feels feels awkward and error-prone though (of course the solr server should be killed while doing _any_ of this). Hmmm, I suppose I could replicate the index to another fresh Solr instance..... Thanks, Erick
