We are in the process of developing a Moodle that allows our teachers to register and take professional development courses. I would like help/advice in setting up a search page for the staff that will retrieve course information given specific criteria that the staff can enter.

I would like the staff to be able to search for available classes with the following criteria: general grade level (elementary, middle, high school), specific grade level (pre-k through 12), department (science, history, mathematics, etc.), key words (constitution, reading for understanding, integration, video, etc.), and start date.

I believe that I will need to add fields to the course settings (such as specific grade level, department, key words). How do I do that?

And how would I set up the search page and the search engine?

Any ideas?
