Yes we expect you to search for existing questions and their answers first and to see whether those answers answer your question. If they don't you can ask a new question and that searching is your research that you should then include in your question. It's how we know what to focus on, we can concentrate on that specific missing piece that you don't understand.
There's a limited group of people that answer questions here. Do you think that what they want to do is answer the same question day after day after day? How long do you think they'd last if we asked them to do such a repetetive task? We want those people who are subject matter experts to expand our body of knowledge and not just have them endlessly repeat things.
If your question is closed as a duplicate and you think its answers don't apply, edit the question and explain why not. Your question should then be reopened so someone can answer it and because you've explained specifically why the existing answers aren't appropriate we can focus on that point.
If the duplicate does apply then you got your answer. Additionally your question can serve as a signpost to that answer if that's helpful.
