Subject [jira] [Commented] (LUCENE-8138) Check that dv producers return the same values with advanceExact
Date Fri, 02 Feb 2018 13:46:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-8138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16350347#comment-16350347
] 

Robert Muir commented on LUCENE-8138:
-------------------------------------

Also because checkindex historically did a sequential pass on the data thru all docs (like
merging), mergeInstance makes it much faster. For example the stored fields reader decompresses
differently for this case.

> Follow-up of LUCENE-8117. I'd like to make CheckIndex verify that doc values producers
return the same values regardless of whether the iterator was moved with nextDoc/advance or
advanceExact.
