Hey there, I have beeb testing the last patch and I think or I am missing something or the way to show the collapsed documents when adjacent collapse can be sometimes confusing: I am using the patch replacing queryComponent for collapseComponent (not using both at same time): <searchComponent name="query" class="org.apache.solr.handler.component.CollapseComponent"> What I have noticed is, imagin you get these results in the search: doc1: id:001 collapseField:ccc doc2: id:002 collapseField:aaa doc3: id:003 collapseField:ccc doc4: id:004 collapseField:bbb
And in the collapse_counts you get: <int name="collapseCount">1</int> <str name="fieldValue">ccc</str> <result name="collapsedDocs" numFound="1" start="0"> <doc> <long name="id">008</long> <str name="content">aaa aaa</str> <str name="col">ccc</str> </doc> </result> Now, how can I know the head document of doc 008? Both 001 and 003 could be... wouldn't make sense to connect in someway the uniqueField with the collapsed documents? Adding something to collapse_counts like: <int name="collapseCount">1</int> <str name="fieldValue">ccc</str> <str name="uniqueFieldId">003</str> I currently have hacked FieldValueCountCollapseCollectorFactory to return: <str name="fieldValue">ccc#003</str> but this respose looks dirty... As I said maybe I am missunderstanding something and this can be knwon in someway. In that case can someone tell me how?
