Recreate an Index?

Hi there,
I accidentally deleted a lot of content from my index directories on my Graylog server. I’ve been told Elasticsearch will generate a new index if graylog sends messages to it. My issue right now is that I can’t delete the index (the default index). How can I delete it so a new one will be created & restore functionality to my server?

Thank you

I would stop Graylog - delete the data via Elasticsearch API. On the start of Graylog it will recreate the indices. Or you can run rotate indices to get a new index for your data.
