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.

wilsonge commented 3 years ago

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 commented 2 years ago

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

ConfidantCommunications commented 2 years ago

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.

Hackwar commented 2 years ago

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

gerdkolano commented 2 years ago

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' JOOMLAROOT/ found JEvent in JOOMLAROOT/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.

hakanara commented 2 years ago

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.

aspergerway commented 2 years ago

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!

aspergerway commented 2 years ago

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!

brianteeman commented 2 years ago

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 commented 2 years ago

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.

I solved it by uninstalling the old search package and all related extensions.

This comment was created with the J!Tracker Application at issues.joomla.org/tracker/joomla-cms/32805.

ConfidantCommunications commented 2 years ago

I can confirm the solution by @aspergerway. Turns out my earlier solution involved copying over an older version of the old search package (I thought it was included with Joomla 4 but it wasn't).

ConfidantCommunications commented 2 years ago

However the Smart Search indexer currently reports "undefined Call to undefined method Joomla\Component\Finder\Administrator\Indexer\Helper::getContentPath()" as some other people are experiencing.

ConfidantCommunications commented 2 years ago

I removed the finder plugins for Phoca Download and now it indexes fine.

Hackwar commented 2 years ago

Please don't post (new) stuff in closed issues. No one is looking at closed issues.

ConfidantCommunications commented 2 years ago

Remember, this is in the spirit of helping out anybody who came here since the issue was closed on January 17. If it is somehow interfering with your workflow then I am sorry.

Hackwar commented 2 years ago

Sorry for being so direct, but the place for support is forum.joomla.org. The original issue was solved by pointing to an update of com_search, everything else after that was unrelated to that.

guntiszarinsh commented 2 years ago

Where can i find any developer documentation for Joomla 4?

alikon commented 2 years ago

https://manual.joomla.org/

guntiszarinsh commented 2 years ago

https://manual.joomla.org/

Funny :) Did you ever visit this site? It is almost empty.

This is unreleased documentation for Joomla! Programmers Documentation v4.3.x (upcoming) version.

Looks like more easily to write new CMS (with blackjack and hookers) that to upgrade my old extensions from J3.x to J4.x

brianteeman commented 2 years ago

Yes that was a very unhelpful link as that site is just beginning.

I would check out this link https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4.

And this one (still a work in progress) https://github.com/nikosdion/joomla_extensions_development

alikon commented 2 years ago

did you know that we are a "real" community driven project ? and all of us do it for free, in their free time ? so my question to you is where is your contribution ? before to complain ask to yourself what i've done to enanche the project did you ?

brianteeman commented 2 years ago

@alikon thats not helpful and as vp I would expect more

guntiszarinsh commented 2 years ago

i hate do that for client 10 years ago... as i hate it do now :) bot they pay :) looks like not all of you do that for free :) chronoforms for sample :) i just looking for some documentation... at least, i will do my job gob trought code... but if your excuse is that you are open free, and so terible, then better dont do that.

For sample, checkout Yii project, comunity and documentation.

alikon commented 2 years ago

i'm sorry to have a completely different perspective from yours, but objective facts must be exposed, and both of you are on the wrong side, first do it and then complain, only complain is not productive

guntiszarinsh commented 2 years ago

This one sometimes helps, but.... for sample JAdministratorHelper::findOption():

JAdministratorHelper has been removed without replacement. (It's been merged into JApplicationAdministrator.)

It is not more static accessable, $this->option not always accessible or null. At least find out $this->app->findOption(), or finally 

$app = \Joomla\CMS\Factory::getApplication()

to get access to App. With JDispatcher same 'shit'... $dispatcher->dispatch() no mo accept array as parameter - costly refactoring, there is solusion as

\Joomla\CMS\Factory::getApplication()->triggerEvent()

but will be deprecated at version 5 (next year? )

Maybe solutions i found is wrrong, but i work only 3 days on issue - upgrade components from J3.x to J4.x. Previous time seen Joomla ~7 years ago.

And this one (still a work in progress) https://github.com/nikosdion/joomla_extensions_development

Still in progress :( (was looking, does ever exist any book about joomla 4) But read again, just to upgrade extensions (last time we spent 3 months for development (if i remember right), this time we dont have so much time)

guntiszarinsh commented 2 years ago

ah and, yes, i was check CMS top - links i visit Joomla was in average top 3. :) If i dont like Joomla so much, how bad is other CMS?
