Hi, I'm planning to upgrade to Solr 4.6 to move from using Result Grouping to CollapsingQParserPlugin. I'm currently using SolrCloud, couple of issues with Result Grouping are :
1. Slow performance 2. Incorrect result count from ngroup My understanding is that CollapsingQParserPlugin is aimed at addressing the performance issue with Result Grouping. Based on the available documentation, I'm not sure if CollapsingQParserPlugin addresses the result count when the collapse field is spread across shards. The Result Grouping ngroup currently works if the groups are not distributed and confined to a dedicated shard. Just wondering if this applies to CollapsingQParserPlugin as well ? Will "<result name="response" *numFound="6"* start="0">" be incorrect if the collapsed field is distributed ? I'll really appreciate if someone can provide pointers on this. Thanks, Shamik
