[jira] [Updated] (LUCENE-8660) Include totalHitsThreshold when
tracking total hits in TopDocsCollector
[ https://issues.apache.org/jira/browse/LUCENE-8660?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jim Ferenczi updated LUCENE-8660:
---------------------------------
Description: Today the total hits threshold in the top docs collector is not inclusive, this means that total hits are tracked up to totalHitsThreshold-1. After discussing with @jpountz we agreed that this is not intuitive to return a lower bound that is equal to totalHitsThreshold even if the count is accurate. (was: Today the total hits threshold in the top docs collector is not inclusive, this means that total hits are tracked up to totalHitsThreshold-1. After discussing with @jpountz we agreed that this is not intuitive to return a lower bound that is equal to totalHitsThreshold even if the count is accurate.
This also means that a threshold of Integer.MAX_VALUE will always return accurate total hits even if the number of matching docs is equal to (Integer.MAX_VALUE-1).)
