I’m trying to solve Lab for Chapter #4, but I don’t have a clue on the path to do that…
I need to find the top 10 for 2 different fields, get the intersection from those 2 arrays, and count the lines on that.
I can’t figure out how to use
facets to solve that. I’m trying to figure out a way to create the 2 arrays with 10 elements. If I understood right,
facet is a way to
group. And I can’t figure out how to use that to generate those arrays.
Hope someone enlightens this for me… Please.
