How do you configured Elasticsearch to run fulltextsearch:index? Nextcloud 20 Snap Ubuntu 20.04

[Jsalas424]

I followed the "Basic Installation" instructions here: https://github.com/nextcloud/fulltextsearch/wiki/Basic-Installation . I'm running Nextcloud snap in Ubuntu 20.04.

I installed elasticsearch with these instructions: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-elasticsearch-on-ubuntu-20-04 and is running

jon@nextcloud:/$ sudo systemctl status elasticsearch
● elasticsearch.service - Elasticsearch

}

But I can't index!

jon@nextcloud:/$ sudo nextcloud.occ fulltextsearch:index

In Index.php line 225:

  Please install php-readline, or use --no-readline  

fulltextsearch:index [--output [OUTPUT]] [-r|--no-readline] [--] [<options>]

Elasticsearch ins't configured properly I guess?

jon@nextcloud:/$ sudo nextcloud.occ fulltextsearch:test

Edit: I got a little farther. I neeeded to include this in my NC config:
