Hi Dariusz, If you use *:* you'll rerank only the top N random documents, as Emir said, that will not produce interesting results probably. If you want to replace the original score, you can take a look at the learning to rank module [1], that would allow you to reassign a new score to the top N documents returned by your query and then reorder them based on that (ignoring the original score, if you want).

That way you’ll get score=1 for all doc and can rerank. The issue with this approach is that you rerank top N and without score they wouldn’t be ordered so it is no-go. What you could do (did not try) in rescoring divide by score (not sure if can access calculated but could calculate) to eliminate score.
