Hi fzliu, Have you considered to add keyword search and other factors into the re-ranker? Other factors are formatted texts like bold, heading, bullet points, as well as bunch of factors typically seen in web search techniques?

Keyword search (or something similar in concept, like bm25) would typically be first stage, rather than second, since it can be done with an inverted index.

  I'm aware of that. My question was around using it in the ranking algorithm.
