Full Text Search does not index files

Hi, I’m having a bit of a strange issue with my OwnCloud server. I have Full Text Search enabled, and up until a few days ago it was running just fine. Something must’ve changed though, as new documents weren’t being indexed by the Elasticsearch database. I reset and tried to rebuild the indexes for all users, but now it doesn’t seem to be indexing anything, telling me on the settings page that it has 0 nodes indexed

Steps to reproduce

  1. Run occ command to reset search index
  2. Run occ command to rebuild index for all users

Expected behaviour

Full text search should be indexing all files and users should be able to search contents of documents

Actual behaviour

Full text search does not seem to be running at all. Searching is completely broken
