Add ingest-attachment plugin to elasticsearch

using nextcloud snap 18.0.4, i have no idea how i can install the plugin ingest-attachment. it might be needed to have the search indexing inside my office and pdf files.

installing the elastic search app and file full text search app was not enough to have it working.
i have to setup separately elasticsearch on my ubuntu and set the server to be localhost:9200.
now Elastic seem to be working, when i run the snap occ command i get this:

$ sudo snap run nextcloud.occ fulltextsearch:test

.Testing your current setup:
Creating mocked content provider. ok
Testing mocked provider: get indexable documents. (2 items) ok
Loading search platform. (Elasticsearch) ok

In IndexService.php line 253:

fulltextsearch:test [–output [OUTPUT]] [-j|–json] [-d|–platform_delay PLATFORM_DELAY]

also here is the check command :
$ sudo snap run nextcloud.occ fulltextsearch:check

i did install the plugin.
but nextcloud still fails to see it when i check.

$ sudo snap run nextcloud.occ fulltextsearch:test

Looks like Elasticsearch is not supported in Nextcloud Snap - read this one: https://github.com/nextcloud/nextcloud-snap/issues/708

i arrived to make the plugin work somehow.
however there is this issue.

thanks @gargancian i will report that to github issues

$ sudo snap run nextcloud.occ fulltextsearch:test

As a note to anyone coming by where the app still won’t connect to ES. After installing ES plugins you have to restart ElasticSearch before the ingest-attachment plugin gets loaded.
