MeiliSearch doesn't seem secure enough for my needs, so I'm opting to use Typesense instead. E.g. no encryption at rest in MeiliSearch and they have no intention to support it.
We support almost all languages. The only thing is that in some languages, without help and intervention from the community, we stop when our level of comprehension is not enough. Today we handle perfectly Latin-based languages and all languages that are space separated. We have also worked with the community to improve Chinese, Japanese, Thai, and Korean, which is under review.
Thanks @qdequelen for pointing out Quickwit :)
