Subject [GitHub] [lucene-solr] jpountz opened a new pull request #1043: LUCENE-9071: Speed up BM25 scores.
Date Thu, 28 Nov 2019 09:33:12 GMT
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.
