So if look at the old SOLR-236 fieldcollapsing (http://wiki.apache.org/solr/FieldCollapsingUncommitted) you mean collapse.type=adjacent ?
I think we shouldn't change group.query parameter. Since it serves a different purpose. I think it is better to have a new parameter for this different way of grouping: group.adjacent=[fieldname|function] I also think it is difficult to support this feature in sharded environment. Since the merging the groups is based on the location of documents inside the result list.
