Support of OpenSearch

[sebix]

I also would love for Zammad to support Opensearch. From what I tried, it looks like it checks and refuses to talk to anything that is not Elasticsearch. I don’t think that should end up in a final error, but a warning.

It checks the version number. Did you follow the instructions in Opensearch + Zammad: Version 2.0.0 of configured elasticsearch is not supported - #3 by sebix ?

Also, it seems like the Debian package depends on elasticsearch|elasticsearch-oss.

You can workaround that by creating a dummy package, that provides elasticsearch:
Prepare the directory:

mkdir elasticsearch-dummy
cd elasticsearch-dummy

create a file elasticsearch-dummy with content

Section: misc
Priority: optional
Standards-Version: 3.9.6

Package: elasticsearch-dummy
Version: 2.3.0-1  # or whatever you want
Maintainer: Your Name <yourname@example.com>
Provides: elasticsearch
Architecture: all
Description: Dummy package for ElasticSearch server
 Dummy package for ElasticSearch server to satisfy dependencies of Zammad package.

Then build it:

equivs-build elasticsearch-dummy

install the resulting .deb-file.
