If it did then I'd be well on my way to fortune and glory. Alas, that is not the case.
The article in my link on recursive CTEs below has a solution to the classic transportation problem. And there are probably ways to improve upon it, given sufficient time and energy.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
