The purpose of this meeting is for you to clarify what your topic is or is becoming by discussing it with your mentor. You should have some ideas about that from your searches and reading, and be prepared to take an active role in the meeting --it's not just an opportunity to say "tell me what you want...", though I anticipate that your faculty mentor will give you some guidance about direction and approach.
You should make entries before and after your appointment, and the latter should reflect whatever advice your faculty mentor gave you about searches and topic development. I hope to see a narrative of your search process, including the search terms you used.
