Hey HN - lead dev on pg_bm25 here. To provide a bit more context: the goal of pg_bm25 is to make BM25-based full text search feel native to Postgres. pg_bm25 is built on Tantivy, a Rust-based alternative to Apache Lucene. We've integrated Tantivy into Postgres as a native index type and introduced a custom SQL operator for executing search queries.
