All I know is that there was a promise:

Notes on Search (com_search)

Search (com_search) will be decoupled in Joomla 4.x. Search (com_search) will migrate to Joomla 4. After migration, you'll need to update it to the Joomla 4.x version via com_installer. It will continue to be maintained, but more the same way a third-party extension is by receiving updates via com_installer. ... earch will still be available at https://extensions.joomla.org/category/official-extensions/.

( https://docs.joomla.org/Joomla_3.x_to_4.x_Step_by_Step_Migration )

I haven't heard any news about that for a long time.

Search was decoupled. There's a branch here containing the fixes. You should have an update site setup on update - see: https://github.com/joomla-extensions/search/blob/4.0-dev/src/components/com_search/Model/SearchModel.php

[Hackwar]

As @wilsonge said, this is something that is solved by properly updating the com_search component. Thus this issue can be closed.

[ConfidantCommunications]

For me, "properly updating" involved manually copying the com_search folders from /administrator/components and /components from a fresh (non-upgraded) install of Joomla 4. If anyone knows of a more sane method please do tell.

That would be really astonishing, since com_search isn't part of Joomla 4 anymore.

I updated from 3.6.10 to 4.1.0. Using the smart search module produced the error
class JEventDispatcher not found.
The command grep -R 'JEvent' JOOMLA__ROOT/
found JEvent in JOOMLA__ROOT/components/com_search/models/search.php
Using in the administrator's backend IExtensions:Manage
I first disabled all search and Search related entries
and then uninstalled all search and Search related entries.

Using System Dashboard >> Update >> Joomla >> Check for Updates
I clicked on
Reinstall Joomla! core files
Success.
The command grep -R 'JEvent' JOOMLA__ROOT/
did not find JEvent any more.

Home Dashboard >> Components >> Smart Search >> Index
showed a lot of entries
and voilà
using the Search feature in the front end succeeded.

Can you please add the link to the component here?
https://downloads.joomla.org/extensions

Also what about the translations of this component. Most probably translaters are not aware of it yet.

I have this problem right away. I did a clean install of joomla 4.1.2 and Helix Ultimate 2.0.7.
Even reinstalling the joomla core the problem does not go away.
Every time I search for something it appears:
0
Class 'JEventDispatcher' not found

What should I do?

To upgrade to joomla 4 I preferred to recreate my site from scratch.
But until I solve this thing I can't go on.
Help me please!

I get the problem.
I had understood that in clean installations the com_search component was not present but the advanced search was present.
So when I created the module I saw Search and chose that one, instead I had to choose the advanced search one.
But if they removed the search component, why the hell was the search module left?
I've been going crazy for a week!

Did you install joomla and then helix - or was it an all in one installation.

I ask because on a clean joomla install there is only one search module so I wonder how you have the module.

[aspergerway]

thanks! Clean installation from joomla.org of joomla 4.1.2, then I installed helix ultimate 2.0.7 only tempate. Both without demo material. Il giorno mer 20 apr 2022 alle ore 10:59 Brian Teeman < ***@***.***> ha scritto:
