NextCloud Docker & Elastic Search - Outdated Index Problem

ℹ️ Support
1

Hi,

I have docker installation of NextCloud 23.0.3 + Elastic Search 7.6, and search yields strange results which seems like outdated Elastic index. How to enable live indexing, or at least, indexing update each hour, for example?

Thanks in advance.

I have run

docker exec --user www-data cloud_app php occ fulltextsearch:test
docker exec --user www-data cloud_app php occ fulltextsearch:check

and there seem to be no problem (logs attached at the bottom).
Then

docker exec --user www-data cloud_app php occ fulltextsearch:index

No problem either. Yet after re-index full text search list is partial and missing many PDF and ODS. Strange enough, some time ago that WORKED.

# docker exec --user www-data cloud_app php occ fulltextsearch:test

Seems like problem with parsing results from Elastic Search.
Anyone know how to fix this?
