I think multi-lingual stemming is the point where I see this as a real ES competitor. Still they've come a long way, and burning too much RAM on ES is not the way fwd either.
I've had a great experience with Meilisearch, it was very easy to set up.
But I'm not sure what's behind the claim that "it supports all languages", aside from handling unicode? Does it support stemming at all? Does it have customized stop words per language?
To answer your question precisely, we handle all the space-separated languages and have specific tokenizers for Chinese, Japanese, Korean, Thai, and Hebrew. We plan to add more languages in the future.
