Search Engine Libraries in Titania

[Skouat]

Hi Team,

I’m opening this issue to discuss the message posted by @iMattPro in this GitHub comment:

This makes me think we should also remove "Zend" as a search engine, then that would allow us to delete the zend and ezcomponents junk in includes/library.

Currently, Titania supports three extra search engines:

• Sphinx
• Solr
• Zend

However, all of these are either outdated or abandoned. Below is a summary of their current status:

Sphinx

• Currently used via the phpBB Sphinx API.
• The API itself is outdated and may require an update or replacement.

Solr

• The current library relies on EzComponents, which is outdated.
• A potential workaround is available using the Zeta Components Composer package: Zeta Components Search.

Zend

• The current library uses the Zend Framework, which has been abandoned and replaced by the Laminas Project.
• Unfortunately, I couldn’t find a replacement library within the Laminas Project for this functionality.

Let’s discuss how we want to proceed with these search engines. Should we explore replacing them, updating their dependencies, or consider removing some altogether?

Looking forward to your thoughts!
