The most specific criticism I have read of Meilisearch is https://news.ycombinator.com/item?id=32940683. It has four points: (1) words beyond 65535 are silently ignored (this is documented in https://docs.meilisearch.com/learn/advanced/known_limitation... ); (2) the position of a matching word in a document non-optionally affects ranking; (3) to get the match information you must retrieve the entire attribute; (4) the meaning of PUT and POST is switched relative to RFC 7231.
Are points (2) through (4) true? Has any of the points been an issue for you in practice?
