Moodle supports context sensitive search?

Hello There,

I am looking into Moodle by installing 2.5 in my virtual environment. One of my purpose is to verify if Moodle supports context sensitive search, especially, after I upload hundreds of courses, how user can search the course or specific topic they are interested in (not just course title, becuase one course can include several features of one software product.), however, I do not find such feature so far.

I see there is a search box on the home page, admin can use it search course title, not content, but student seems can do nothing.

Do you have exeperience already on this?

Thank you,

Anson
