Subject [jira] Commented: (SOLR-1682) Implement CollapseComponent
Date Tue, 17 Aug 2010 01:55:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12899235#action_12899235
] 

Yonik Seeley commented on SOLR-1682:
------------------------------------

OK, so if I'm reading the patch correctly, it looks like the new group.sort you added decouples
the sort of the groups from the sort of the documents within each group?  (and group.sort
specifies the sort of the docs *within* each group?)

What's the intended semantics of how to sort the groups?  For example: if I'm sorting the
documents within each group by price desc, and I'm sorting the groups by popularity desc...
what if the top docs kept in group A (those with the highest price) are not the docs with
the highest  popularity?  Are groups sorted by the popularity of the first doc (i.e. the one
with the highest price), or are they sorted by the highest popularity doc with group value
A (even if it's not in the top N in that group)?
