Thank you for the opportunity to help you with your question!

Sure, not an issue but it will mean you can get multiple hits for the same query.

You have to take that into account in your program.

Guidance is to have a unique key for every table but that is not a requirement

Please let me know if you need any clarification. I'm always happy to answer your questions.
