I was reading this documentation on Result Grouping... http://docs.lucidworks.com/display/solr/Result+Grouping
which says... sort - sortspec - Specifies how Solr sorts the groups relative to each other. For example, sort=popularity desc will cause the groups to be sorted according to the highest popularity document in each group. The default value is score desc. group.sort - sort.spec - Specifies how Solr sorts documents within a single group. The default value is score desc. Is it possible to use these parameters such that group.sort would first sort with in each group, and then the overall sort would be applied according to the first element of each sorted group ? For example, using the scenario above where it has "sort=popularity desc", could you also have "group.sort=date asc" resulting in the the most recent document of each group being sorted by decreasing popularity ? It seems to work the way I described when running a single node Solr 4.3 instance, but in a 2 shard configuration it appears to work differently. -Bryan
