I have created a question in Stackoverflow. A user pointed out that there are a lot of similar questions, suggesting to read their answers and then update my question. It is possible that none of them have the (whole) answer I need. It is possible that the intersection of that answers can be the answer to my question (1), or not (2).
What should I do? I think best way is to update my question writing why that questions are not useful when (2) happens. If (1), should I answer my own question, or should I delete the question (leaving the question could lead to a partial duplicate)?
