> I am digging into some performance regressions between 4.x and 5.x which seem
> to be due to how we always run conjunctions with ConjunctionDISI now while
> 4.x had FilteredQuery, which was optimized for the case that there are only
> two clauses or that one of the clause supports random access. I'd like to
> explore the former in this issue.
