    [ https://issues.apache.org/jira/browse/LUCENE-9328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17138772#comment-17138772 ] 

Mikhail Khludnev commented on LUCENE-9328:
------------------------------------------

Recently, the following wrong statement brought up in te mailing list
{quote}From the DocValues documentation ([https://lucene.apache.org/solr/guide/8_3/docvalues.html]), it mentions that this approach promises to make lookups for faceting, sorting and grouping much faster.
{quote}
I suppose until it's resolved, I propose to remove grouping from the list of beneficiaries. WDYT?
