You've given us expected results, which is a good thing. Some people like me visualize solutions most easily when this is provided.
However you have not provided DDL for your tables, nor INSERTs (setups) for your sample data. And the format that you posted them in would be a pain to convert.
I think if you do this, someone is going to be able to make short work of your question.
Remember we're all volunteers here. 🙂
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.
