Hi Martjin Sorry for a late response.
I did take the latest Solr build last week. After the new snapshot, there was a class called grouped response: (org.apache.solr.client.solrj.response.GroupResponse) But, the Solrj snapshot (apache-solr-solrj-3.4-SNAPSHOT.jar)'s QueryResponse class did not have a method: getGroupedResponse(). Is there something I am missing? S. On Wed, Aug 31, 2011 at 2:55 PM, Martijn v Groningen < martijn.v.gronin...@gmail.com> wrote: > The CollapseComponent was never comitted.
