How to use two index hint in Oracle?

Excuse me, could you please elaborate on how to effectively utilize two index hints in Oracle? I understand that index hints can significantly enhance query performance by directing the optimizer to use specific indexes. However, I'm unsure about the syntax and best practices when incorporating two such hints into a query. Could you provide a concise example, highlighting the steps and considerations involved in this process? It would be greatly appreciated if you could also touch upon any potential pitfalls or limitations I should be aware of.
