> When {{\{!auxIndexJoin}}} got no sibling filter (including {{fq}}) there's no
> sense to bother with lazy two phase iteration.
> Let's just defer the decision about that up to {{AIJScorerSupplier.get()}}
> and when it got {{SS.get(cost==MAX)}} means there's no sibling filter, skip
> approximation just eagerly drain all columns onto to-size bitsets.
