It used 145 core-seconds of compute, according to the paper. That's not 100% unless they were mostly 1 core servers.
However, the search used almost 50MiB of traffic before the query was even sent by the client. I imagine that will add up fast.

You’re right, I did my math with 1 core assumption. Still, it’s 800ms of 100% utilization of all 4 vCPUs across the entire cluster. That’s 40% capacity if the 2s latency was purely CPU bound and the current was next to the server, but we know the initial phase involves some round trips to communicate that 50mib so the 40% is a floor. My point remains that this is several orders of magnitude off in terms of cost still (as you mention network bandwidth required is off by similar orders of magnitude as cpu).
