thank you , Erick,
i want to sort groups based on the sum of documents' scores within each
group, as you said, solr excels at getting the score of single documents, in
solr 4.6, the default sort of group each other depends on the maxScore of
all documents within each group, but the sum of documents' scores, though i
can get the sum of documents' scores by the client program, it's not good
idea, l know that the stats component of solr can statistics the long field,
so I had the idea to use statistic data for score field, but the score is
pse-udo field, the stats.field doesn't support it. In addition, as
scheme.xml displayed, i do group on the elements of a string field(type)
without using participle.
