Michael McCandless commented on LUCENE-4715: -------------------------------------------- +1 This is very compelling because you also do not need to do the rollup in the end, so you get the gains of NO_PARENTS without the cost (end rollup), so even for indices w/ many unique ords there's no penalty. I also suspect this is common ... ie most faceted search UIs I've seen do not include the dim facet count, just the values under that dim. > Add OrdinalPolicy.ALL_BUT_DIMENSION > ----------------------------------- > > Key: LUCENE-4715 > URL: https://issues.apache.org/jira/browse/LUCENE-4715 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/facet > Reporter: Shai Erera > Assignee: Shai Erera > > With the move of OrdinalPolicy to CategoryListParams, > NonTopLevelOrdinalPolicy was nuked. It might be good to restore it, as > another enum value of OrdinalPolicy. > It's the same like ALL_PARENTS, only doesn't add the dimension ordinal, which > could save space as well as computation time. It's good for when you don't > care about the count of Date/, but only about its children counts. -- This message is automatically generated by JIRA.
