Hi everyone! I'm using

group_by

and

sort_by

together.

sort_by

seems to sort within each group. How can I sort the groups themselves? For example, if I group products by store (3 best product matches per store), how can I sort the groups by store rating?

The sorting works like this: within each group we sort by the sort criteria and then the lowest/highest document (depending on asc/dssc ordering) is picked to represent the group and all the results are ordered using that document. In short, you can't have an inner and outer sort orders.
