Nextcloud and Full Text Search

Donahue

I have installed NC as per @JaredBusch's great guide. Now however, I want to enable both full text search and OCR for the files in NC, but I am running into issues, probably because I don't know a whole lot about linux in general and fedora in specific. A lot of the guides that I am finding online seem to be for debian or ubuntu.

So far, I have installed the 4 apps currently in the NC appstore for full text search.

But when I attempt to run the first index, following this guide I get this error:

[root@Nextcloud ~]# sudo -u apache php /var/www/html/nextcloud/occ fulltextsearch:index

In Index.php line 379:

  failed platform test.


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

If I run a test, it shows that the platform is down:

[root@Nextcloud ~]# sudo -u apache php /var/www/html/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
Testing search platform. fail
In Test.php line 300:

  Search platform (Elasticsearch) down ?


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

If I try and enable the elasticsearch service, I get this:

[root@Nextcloud ~]# sudo systemctl enable elasticsearch
Failed to enable unit: Unit file elasticsearch.service does not exist.

All this leads me to believe that the app method of installation does not work right, maybe just on fedora? Other methods of installation have different syntax, and I am struggling to figure out how to translate it to fedora.

Looking at the official install guide here, It looks like I need to add the elastic.co repository, but it is https, and so I need to enable that. If I try and just run sudo dnf install elasticsearch it complains about nothing providing it's requirements, so that leads me to believe it needs that other repository.

the guide shows this for debian:

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list
sudo apt-get update && sudo apt-get install elasticsearch

what should this be for fedora?

@Donahue That says other required pieces are not available. Not that elasticsearch was not available.

JaredBusch

Which does not surprise me since it is from Fedora 24.

And that was hard to find.

Typo in my search text and everything...

Donahue

I find it odd that the elasticsearch app is installed in NC, but the package is not on my machine.

Donahue

I was able to get it installed using that link and also here: https://www.linode.com/docs/databases/elasticsearch/a-guide-to-elasticsearch-plugins/

After that, I can run the index and it picks up new documents. But it will not search them.

Donahue

It seems the search only works on files that are not shared.

Not really, nothing "in" NC shows up as a package on your machine. NC is its own thing, things inside of it would not be expected to be system packages.

Donahue

So to update this, searches do not seem to work in shared folders, but they will work in group folders which is an optional app. I also had to setup the backup job in NC to be a cron job and not an ajax job, and add it to the crontab for the apache user.

crontab -u apache -e

I couldn't get the fulltextsearch:live to work properly, so I added fulltextsearch:index to the cron job too.
