Hello. I'm extremely new to managing an elastic stack, so it is not something I am familiar with. The implementation we have right now is encountering issues, and after trouble shooting for some time I believe it is due the amount of data being indexed. I have attempted to delete the indicese from the past few months, and they show as deleted for a small amount of time. However, they come back as red and unallocated. I want them permanently gone. I have been using the dev console and also tried with curl commands as below:
curl -XDELETE http://elastic-url/common-index-name*
Any help would be greatly appreciated.
