I tried turning tracing on and then running a Solr query through CQL, but the trace stopped at the top of Solr and just gave summary stats about the Solr results.
What I want to know is how many joins happened, and how many documents each search term matched. I want to know how expensive each join was (how much it contributed to the latency of the search). I also want to know how many filter cache entries got reused (or had to get recalculated).
Is there a way to do this with DSE query tracing? If not, is there a way to do this with Solr?
