Yes, should be no problem. Although this should be happening automatically, the percentage of documents in a segment weighs quite heavily when the decision is made to merge segments in the background.
You say you have "millions of deletes". Is this the difference between numDocs and maxDoc on the admin page for the core in question? Or is it just that you've issued millions of updates (or deletes)? Because if the latter, I'd advise monitoring the numDocs/maxDoc pair to see if the problem goes away on its own. bq: ...and need free space This is a red flag. If you're talking about disk space, before you get the free space forceMerge will copy the _entire_ index so you'll need at least 2x the current index size.
