CDJ 1000

I am completely new to the whole CDJ and mixing world, but I just have a question about the CDJ 1000. I know that the CDJ 1000 doesn't have a usb option to import music, It only uses cds. Now if I put all the tracks on a cd that i want to use, can I select them with the track search? Is that what the option is for? To select tracks? Sorry this is probably a really dumb question. I am new, just curious!
