Hello. I just tried to patch Solr 1.4 with the field collapsing patch of https://issues.apache.org/jira/browse/SOLR-236. The patching and build process seemed to be ok (below are the steps I did), but the field collapsing feature doesn't seem to work. When I go to `http://localhost:8982/solr/select/?q=*:*` I correctly get 10 documents as result. When going to `http://localhost:8982/solr/select/?q=*:*&collapse=true&collapse.field=tag_name_ss&collapse.max=1` (tag_name_ss is surely a field with content) I get the same 10 docs as result back. No further information regarding the field collapsing. What do I miss? Do I have to activate it somehow?
* Downloaded [Solr](http://apache.lauf-forum.at//lucene/solr/1.4.1/apache-solr-1.4.1.tgz) * Downloaded [SOLR-236-1_4_1-paging-totals-working.patch](https://issues.apache.org/jira/secure/attachment/12459716/SOLR-236-1_4_1-paging-totals-working.patch) * Changed line 2837 of that patch to `@@ -0,0 +1,511 @@` (regarding this [comment](https://issues.apache.org/jira/browse/SOLR-236?focusedCommentId=12932905&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12932905)) * Downloaded [SOLR-236-1_4_1-NPEfix.patch](https://issues.apache.org/jira/secure/attachment/12470202/SOLR-236-1_4_1-NPEfix.patch) * Extracted the Solr archive * Applied both patches: ** `cd apache-solr-1.4.1` ** `patch -p0 < ../SOLR-236-1_4_1-paging-totals-working.patch` ** `patch -p0 < ../SOLR-236-1_4_1-NPEfix.patch` * Build Solr ** `ant clean` ** `ant example` ... tells me "BUILD SUCCESSFUL" * Reindexed everything (using Sunspot Solr) * Solr info tells me correctly "Solr Specification Version: 1.4.1.2011.03.14.04.29.20" Kai
