> Brought to light in part in PHOENIX-5109, plan selection in Phoenix is too complicated with its logic spread over multiple areas. My recent changes let most index through the initial filters and next step is to put all the logic in {{QueryOptimizer.orderPlansBestToWorst}}.
> One exception is plans with global indexes for queries with uncovered queries, those should still be handled in {{addPlan}}.
