   Hmm... not sure if I've got something setup incorrectly with my JFR 
settings, but trying to dig into the other tasks, I can't even get the relevant 
methods to show up in the profiled calls. I attached a debugger and made sure 
the call flow is what I expect, but I'm not seeing any of the term intersection 
logic in what's getting profiled. My theory is that the term intersection is so 
trivial relative to the actually work of computing the postings disjunction 
that it's just not showing up in the samples, but maybe there's a setting I'm 
missing that's not sampling in a fine-enough grain? Not sure. But as far as I 
can tell, with the non-PK tasks, it looks like the term intersection may just 
be such a trivial part of the query cost that it doesn't matter what approach 
we take.
