Personally, I also compare it to using Meilisearch. What I find there is a superb doc, ease of use, full support for other European languages, possibility of sorting by field in addition to BM25, custom stop words (even better if the stop words for each language are already defined), custom ordering. If I could find all this in a Postgresql extension, it would be a dream. Congrats for the progress made, I'll give it a try!

As someone who has used Sphinx search for a long time, and wound up using Manticore after it got forked off of Sphinx, I found that it does much better than the native PostgreSQL search, while not being as resource hungry as Elastic. Especially because it's flexible and can pull from PostgreSQL (and usually the next step after the built in PostgreSQL FTS, for me), it's definitely something I'd be weighing any new search tooling in Postgres (such as yours or ParadeDB's) against.
