Thanks. As this will impact Algolia I'll test it on docs-next first, hence changing the target branch.

I'm not forgetting about this one, @Boegie19.
We'll have an intern working iforn the Strapi documentation in a few months from now, and that should give us more bandwidth to work on improving search. I'll get back to you about it early next year. This + AI chatbot integration should vastly improve the search experience :)
