[jira] [Commented] (LUCENE-10458) BoundedDocSetIdIterator may supply error count in Weigth#count(LeafReaderContext) when missingValue enables
[ https://issues.apache.org/jira/browse/LUCENE-10458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17502773#comment-17502773 ]
Lu Xugang commented on LUCENE-10458:
------------------------------------
That is why in BoundedDocSetIdIterator#advance(int target), target need to be check if such Document contains DocValues

> URL: https://issues.apache.org/jira/browse/LUCENE-10458
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Lu Xugang
> Priority: Major
>
> When IndexSortSortedNumericDocValuesRangeQuery can take advantage of index sort, Weight#count will use BoundedDocSetIdIterator's lastDoc and firstDoc to calculate count, but if missingValue enables, those Documents which not contain DocValues may be involved in calculating count.
