package search results empty - package index for rhn-search does not seem to be created after restart of container

Question

Not sure if this is a question or a bug.
We are running a containerized uyuni-server 2024.07 which was recently migrated from a legacy setup (also 2024.07).
The original server has been running for a few years with a number of software channels, so it contains quite a few packages.
After restarting the container and then trying a package search in the Web GUi (eg 'kernel'), it always returns no packages.
No error - just no matching packages found.
When looking into this I realized that /var/lib/rhn/search/indexes/ is not part of a persistent volume so these indexes need to be recreated every time the container starts. Which looks like it does fine for hwdevice, server, etc., but not for the package folder. While the WebGUI just states no packages found, the /var/log/rhn/search/rhn-search.log states
ERROR - no segments* file found in org.apache.lucene.store.FSDirectory@/var/lib/rhn/search/indexes/package: files:
for each search request done in the GUI.
I also checked for errors suggested in other tickets related to rhn-search, like OutOufMemory ones but could not find any.
I then tried rhn-search cleanindex and the indexes get recreated which fixes the issue.

So my question is when or by which bunch the package index is supposed to be refreshed/recreated after a restart of the container?
To give more context we are running a daily backup routine and are stopping and starting the container for that.
So maybe this is just a matter of us needing to reschedule things a bit.

@fd-SR thanks for reporting it.
@cbosdo seems we missed to persist /var/lib/rhn/search/indexes/

[cbosdo]

Either we persist them or we recreate them at container startup

Re-creating the index may take long depending on how many data you have.
It indexes all packages and all systems. This can take multiple hours

We must persist the search indexes, as Michael says, it can take several hour in worth case
