George P. Stathis updated SOLR-2072:
------------------------------------
Attachment: SOLR-2072-01.patch
Attaching a first prototype pass with a unit test to get the conversation
going. I'm pretty sure this is not going to win any performance contests but
it's still worth sparking some discussion around it. The prototype shows an
implementation of a sum(scores) group sort. The approach basically relaxes the
visibility of some AbstractFirstPassGroupingCollector properties so that
sub-classes can do more with the state encapsulated in the abstract class. A
new collector is introduced based on TermFirstPassGroupingCollector but
implementing its' own collect method. A specialized comparator is used to sum
up the document scores for each group.
Looking forward to some feedback.
