    Description

      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.
