You always start with a search. You want something, you know what you want to find. I think the structure is important for discovery ie API docs. Knowledge bases often lack content that’s why stack* sites exist. You can check apple support, its multi-step process where in each step they ask you a question which narrows down possible issues. I think this is foolproof for problem diagnostics.
