Thanks Erick for your answer, we have huge index 700Gb, 350 millions of documents We had a case of log flooding due to a bug in an application, that generate 100 000 000 documents, so we have deleted them, but there is no impact on indexSize without optimize. I think it's normal, true ?

Some anecdotal reports are 5%-10%. Some higher. Some lower. About the only time I recommend optimizing is if you have a relatively static index, i.e. one that's say updated once/day. For continuously-changing indexes I generally don't recommend optimizing for a variety of reasons.
