Personally, I like these sorts of questions. Knowing the official name of something can unlock a huge trove of resources for learning more about it. Yes, sometimes, there doesn't happen to be a good name. There are two problems with penalizing a question in that case:
- The asker has no way of knowing there isn't an official name when they ask the question.
- The voter has no way of knowing there isn't an official name when they vote.
All you can say is you don't know the name. There has been more than one occasion where people said there isn't a name and someone else provided it. Even if there isn't a single canonical answer, knowing what experienced developers might search for to gain more information is very valuable. This isn't the kind of field where we can eliminate all questions where there isn't a single canonical answer. Those are all the most interesting and useful questions.
