In case you missed it, `BooleanScorer` had optimizations recently that make
it hard to beat by `DisjunctionScorer` when clauses are `PostingsEnum`s:
- `DocIdSetIterator#intoBitSet` helps impls optimize loading matches into
bit sets, in the case of `PostingsEnum` through (auto) vectorization
(annotation [`HR`](https://benchmarks.mikemccandless.com/CountOrHighHigh.html))
- Dense blocks of postings are stored as bit sets, further speeding up
OR-ing postings into a bit set ([annotations `HW` and
`HX`](https://benchmarks.mikemccandless.com/CountOrHighHigh.html))
