To give you a more concrete example, let's say you're writing a story where a character is accused of witchcraft. You've come to the scene where she's interrogated and are looking for inspiration.
This question would be on topic: "I found x, y, z. What are some other ways that people tested for witchcraft?" This question would not: "Help me come up with new ways to test her for witchcraft!"
