There should be an action called "Reindex Data" in the action manual under Index Management according to user manual, but I don't seem to have it. I am using Magento CE 2.30 and pretty certain I am reading manual for Magento Open Source 2.3.
Hello @WZ_OZES
Yes i have compare both Magento 2.3.0 Version and its user guide as well - https://docs.magento.com/m2/ce/user_guide/system/index-management.html
You are correct - on the user guide they have mentioned that we can do reindexing from the action tab by choosing reindex option.
But may be that's the typo error ! because in magento 2 ( Any version ) We don't have option to do reindexing from the backend !
We always needs to reindexing from the command line terminal by running - php bin/magento indexer:reindex command.
Hope it helps !
Hello @WZ_OZES
@Manthan Dave is correct, there is no way you can reindex from backend in default Magento 2.
However if you would like to use this free extension available on github
https://github.com/magepal/magento2-reindex
You might want to use any extension from Adobe Commerce Marketplace. One of the extension which I have used is https://commercemarketplace.adobe.com/cssoft-manuallyreindexing.html
I used in Magento 2.4.7 and it works
