Subject [jira] [Created] (LUCENE-7839) Optimize the default NormsFormat for the case that all norms are in 0..16
Date Thu, 18 May 2017 14:51:04 GMT
Adrien Grand created LUCENE-7839:
------------------------------------

             Summary: Optimize the default NormsFormat for the case that all norms are in
0..16
                 Key: LUCENE-7839
                 URL: https://issues.apache.org/jira/browse/LUCENE-7839
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Adrien Grand
            Priority: Minor


Given how we now store the length of the field in norms, we could optimize the default norms
format for the case that all norms are in 0..16 and store it on 4 bits. This would be picked
up for short fields that have less than 16 terms (eg. title fields) and reduce disk utilization
by 2.
