If you aren't getting the join functionality you want with the current join
implementations you could try the reduce function using the group
operation.
Here is the sample syntax:
reduce(search(collection1, q=*:*, fl="id,a_s,a_i,a_f", sort="a_s asc, a_f asc"),
by="a_s",
group(sort="a_f desc", n="4")
)
The is a basic map/reduce grouping operation.
