[jira] [Updated] (LUCENE-9541) BitSetConjunctionDISI can advance to
docs before its components
[ https://issues.apache.org/jira/browse/LUCENE-9541?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mayya Sharipova updated LUCENE-9541:
------------------------------------
Description:
Not completely sure if this is a bug.
BitSetConjuctionDISI advances based on its lead – DocIdSetIterator iterator, and doesn't consider that its another component – BitSetIterator may have already advanced passed a certain doc. This may result in duplicate documents.
This behaviour was exposed in this [PR|https://github.com/apache/lucene-solr/pull/1903].
