jpountz opened a new pull request #1043: LUCENE-9071: Speed up BM25 scores. URL: https://github.com/apache/lucene-solr/pull/1043 The approach of this change is to try to detect when computing the tf component of the BM25 score would return the same result in float and double space. In order to make this condition likely, it trades little precision from the norm by rounding to the nearest float that has 10 trailing zeros.
