There are GitHub
repositories created by individual developers and then there's the official repository used by the CMS development team; we shouldn't confuse private GitHub
repos with the official one or any claims made by individual people about what may or may not be "supported". I could not say with certainty if the old com_search package
will operate (with modifications) with J! 4.x
going forward but I would doubt it.
The built-in search facilities that exists in J!—whatever version we may discuss—are bare-boned ways of searching the content in a website. Arguably, more advanced, reliable (or better) techniques for searching website content are to use Google
or other internet-based search engine. As more content is added to a website the ability to search that content using the core CMS search facilities becomes less reliable over time and puts a bigger strain on the server used to host it and involves more workload for the site developer to maintain the functionality.
Whether or not the suggestion that any form of the com_search package "is going to be supported until Joomla 5.0 is going to be released" is speculative. I don't believe that it works and we can't be assured that future releases of J! 4.x
will continue to work with it. Officially, the Search
component, plugins and modules were retired before the release of J! 4.0.0; these extensions lingered for a while with releases of J! 4.0 before but even the CMS developers gave up attempts to integrate them with J! 4.0.
As far as I'm concerned, Search
is dead for J! 4.x
. If someone wants to make it work then that's their business but I don't think there's much appetite for it. In conclusion, if people want to use Search
instead of Smart Search
they should stay with J! 3.x
. If people have migrated to J! 4.x
then one of the consequences in doing that is to forget about Search
and accept that it won't work with the new version(s); if you can modify Search
so that it does work, more kudos to you than the CMS development team and I wish you the best of luck if you succeed.
