I have just converted existing Elastic Search app to Meilisearch.
Please work on this software with me if you need it.
I updated it: GitHub - Rubilmax/fulltextsearch_meilisearch: 🔍 Use Meilisearch to index the content of your Nextcloud
Working with nextcloud 33 and latest meilisearch
this sounds great, like to try. But I cannot find the connector for nextcloud as described (https://github.com/nextcloud/fulltextsearch_meilisearch.git)
Where I’m wrong 
you are not wrong, such an address does not exist.
But this is mentioned in the post of Rubilmax. If there is no connector for meilisearch, I don’t understand how to use meilisearch for NC?
In any thing I think there is no practical use for it in NC AIO on Synology, because after every restart of the containers for the daily backup the fulltext search checkbox is unchecked because of the missing seccomp 
You need to use the software from the top post. But I Have never tested it on Synology, though.
