Hi. Nice project! I don't know why there's no BM25 (or at least SOME TF-IDF implementation) in Postgres FTS, but if you decide you need it (and more languages support and highlighting and lower response time) ping us at [email protected] and we'll help you with integrating your postgres dataset with Manticore Search. 60M docs shouldn't be a problem at all (should take about an hour to make an index) and you'll get proper ranking and nice highlighting with just few lines of new code. Here's an interactive course about indexing from mysql https://play.manticoresearch.com/mysql/ , but with postgres it's the same.
