@Duga Does not invalidate answer, question should not have been answered yet.
brute force is not a sin. Pondering about how slow it would be will not make it any faster. Write the code and you will see. If you need help with some code you wrote you should include a minimal reproducible example.

Q: Should i throw exceptions in the service layer or repository, and catch it on the controller?

ThiagoI read some answers here on stack exchange, but none really "hits the nail on the head" about where to throw exceptions, where I shouldn't and where to catch them. the idea that an exception should be thrown in exceptional cases is very vague, for example, if I can't find a user in my data source...

Welcome to Stack Overflow. Please read about what's on-topic in the help center. We need a clear problem statement here. Asking us to review your code is both (a) too broad and (b) too opinion-based to be on-topic. Does this code do what you want it to do? If so, you might try posting on Code Review. If not, please edit it to clearly explain what the problem is. — Chris 46 secs ago

If your code is working properly and you are simply looking for feedback on how to improve it in some way, then you may want to look at Code Review. However, please make sure to look at their help center before posting there, as I don't think this question would be accepted there in its current form. — user 8 secs ago

Is it acceptable here to put suggestions in comments, or must one post an answer even if there's not much to say?
@user If you want to review the code in the question please post an answer, as comments are ephemeral.
Most comments can just be posted as-is and would be upvoteable
Alright, I'll do that
