I'm trying to use facets alongside grouping, however when I ask SOLR to compute grouped facet counts (group.facet=true, see http://wiki.apache.org/solr/FieldCollapsing) it no longer honours facet.query excludes, however without this (group.facet=false) the exclude works again without any problems. Have I mis-understood the purpose of group.facet or is there, as it appears to me, a bug in SOLR 4.1?
Here is the simplest version of a query that shows the problem I'm having: http://localhost:8080/wmp/product/select ?q=title_search:history &rows=0 &fq={!tag=format}formatLegend:Paperback &group=true &group.field=titleCode &group.limit=99999 &group.facet=true &facet=true &facet.query={!key=Paperback ex=format}formatLegend:Paperback &facet.query={!key=Hardback ex=format}formatLegend:Hardback This produces: <lst name="facet_queries"> <int name="Paperback">1492</int> <int name="Hardback">0</int> </lst> However just switching group.facet=false, the following is produced, showing the exclude appears to have been ignored previously: <lst name="facet_queries"> <int name="Paperback">1492</int> <int name="Hardback">1361</int> </lst> Anybody else tried using this combination of excludes, facet queries and grouping and got this working? Kind Regards, Mark
