Hi John, let me try to recap : Your Solr Document is an Item with a price as one of the fields, a purchaseGroupId a groupId. You filter by purchaseGroupId and then you group by ( or collapse by the groupId). At this point how do you want to assign the score ? For each document in a groupId you want to calculate the score as : Max price - min price per ItemId ? How do you want to sort the groups then ? A simple score desc ?
So you have a : purchase_group_id group_id item_id ?
