Hello Chantal! Thanks for your reply!
Actually, in my case, faceting will not help me because I really need all "rows" from the same group at index time. That's because I'll use all rows from the same group, merge them all into a Velocity (or any other template engine) to generate an HTML that will have all items information and willbe queries with the group id param. For example, the select will return all stores (group) and departments (item) in my system. I'll generate an index with N docs, each one with the store id (group) and the final HTML for all its departments! Got it? What you are doing, is any similar to this? Thanks!
