Mikhail Khludnev commented on LUCENE-9328: ------------------------------------------ Ok. [~romseygeek], thanks for the clue. It turns to be more complex problem. I pushed some broken code to github PR https://github.com/apache/lucene-solr/pull/1462/. Currently I'm stuck at [ToParentDocValues.advanceExact()|https://github.com/apache/lucene-solr/blob/master/lucene/join/src/java/org/apache/lucene/search/join/ToParentDocValues.java#L259] which turns it to strict {{advance()}}. I think it's can be changed to use {{advanceExact()}}. Does it make any sense? > SortingGroupHead to reuse DocValues > ----------------------------------- > > Key: LUCENE-9328 > URL: https://issues.apache.org/jira/browse/LUCENE-9328 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/grouping > Reporter: Mikhail Khludnev > Assignee: Mikhail Khludnev > Priority: Minor > Attachments: LUCENE-9328.patch, LUCENE-9328.patch, LUCENE-9328.patch > > Time Spent: 50m > Remaining Estimate: 0h > > That's why > https://issues.apache.org/jira/browse/LUCENE-7701?focusedCommentId=17084365&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17084365 -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
