Subject [jira] [Commented] (SOLR-2553) Nested Field Collapsing
Date Sun, 29 May 2011 17:47:47 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13040837#comment-13040837
] 

Michael McCandless commented on SOLR-2553:
------------------------------------------

I think to represent this returned result we need to have GroupDocs extend TopDocs?  This
way a GroupDocs, which currently uses TopDocs to hold each group's results, is free to recursively
contain another GroupDocs.

> Currently specifying grouping on multiple fields returns multiple datasets. 
> It would be nice if Solr supported cascading / nested grouping by applying the first
group over the entire result set, the next over each group and so forth and so forth. 
> Even if limited to supporting nesting grouping 2 levels deep would cover alot of use
cases.
