Hi Solr users!
Could any of you tell me how to do a facet count across several cores excluding duplicates. Eg. Core A: Page 1 Id=a Text=hello world Page 2 Id=b Text=hello again Core B: Page 1 Id=a Text=Hej verden Id=c Text=Ny besked Doing a facet count on core A gives me 2 elements. Doing a facet count on core B gives me two element as well. Counting across both cores using shards should return 3 elements when doing group.truncate on the element with Id=a. This would work on a single core, but doing so on more than one core always gives me a facet count = 4. I've read the solr page <http://wiki.apache.org/solr/FieldCollapsing#Known_Limitations> saying Grouping is also supported for distributed searches from version <!> <http://wiki.apache.org/solr/Solr3.5> Solr3.5 and from version <!> <http://wiki.apache.org/solr/Solr4.0> Solr4.0. Currently group.truncate and group.func are the only parameters that aren't supported for distributed searches. Is this because it's not possible to make this feature, or is it because nobody needed it yet? Thanks guys :) Kind regards Kenneth Vindum
