Thank you for the feedback. You should probably look at our blog post explaining how to index in smarter way [1]. You should probably come and talk to us on Discord. We work with MrBeast and they don't have any issue indexing millions of YouTube videos everyday.
Ho! And just to tease you a little bit. We highly improved the indexing speed of Meilisearch v1.6 (january 24). Here is a teasing tweet [2].
a lot of people will never read your blog, or visit your discord but would be quite interested in using a tool like meilisearch. you're correct that the information is out there, but unless you put it right in front of them, such people will have a bad time (and sometimes complain about it, publicly!).
