That’s odd, are you absolutely sure that there’s no indexing going on while the optimize is running?
Optimizing only works on the closed segments that exist when the process _starts_, any updates that come in while the optimize is running will result in new segments that are not optimized and if any of the new updates are of docs that exist when the optimize starts, you’ll have deleted docs at the end. BTW, optimizing is generally unnecessary, be sure you need it. Although 7.7 is much better about some of the consequences than previous versions, see: https://lucidworks.com/post/solr-and-optimizing-your-index-take-ii/ If you are not adding docs to the index and still see deleted docs after optimizing, it would be helpful to have the exact steps you use to try to track down Best, Erick > On May 11, 2020, at 2:21 AM, Rajdeep Sahoo <rajdeepsahoo2...@gmail.com> wrote: > > Hi all, > We are using solr 7.7.2 .
